Unfortunately there is no way for the innocent youth of Gaza to rid themselves of Hamas. In fact Hamas actively endoctrinates the youth.
The only way for Gazan youth to be saved from a cycle of terrorist-led hatred is for Israel (or another developed power) to remove the terrorists.
What happened to them? I don't know, but their land is now claimed as a part of Israel. I don't believe they gave it up willingly. Back when people were debating genocide, one of the arguments was that there's more Palestinians than ever before. It used to be ~1 mil over the various states of Palestine, now it's ~5 mil in West Bank and Gaza, and many more all over the world.
The only ones left are the militants because everyone who tried everything else were killed or displaced.
If I were in charge, I would create the circumstances that prevent poverty, create work, and encourage cooperation between both nations hoping that time will heal the hate and anger that both sides accumulated over the years, this requires wisdom and patience from the political party that is smart enough to understand that neither party can redeem the whole land for themselves.
But as long as each party refuses to accept the other, regardless if they say it publicly or not the hate will never end.
Israel was biggest employer of palestinians from gaza and west bank. In fact, week before oct 7 number of work permits for gazans went up by 10k or 15k. This was because there were thought that economically stable gaza will be less likely violent and that hamas is somewhat interested in state building and prosperity. In aftermath of oct 7th turned out that workers from gaza (with permits) were scouting areas where they worked in order to make a detailed maps for attack and a bunch of attackers actually carried work permits.
when israel left gaza in 2005, inside israel was popular expression that "now that palestinians have complete self rule there, it's up to them what to build there, singapore or somali".
there is an israeli investor [1] who created design center in gaza, donated there money to hospital and employed palestinians from gaza and west bank. he daugher was murdered at nova. a bunch of people who lived in kibutzim around gaza were hardcore left and used to drive palestinians from gaza to treatments in israeli hospitals. they were murdered as well.

Also Israel never left Gaza. They had complete control over the sea air and land entry and exit points. Gaza was essentially an open-air concentration camp. They even calculated the minimum calories required so that Palestinians would not be "overfed". I'm in constant disbelief about the nonsense that Zionists tell themselves.
There's no significant Hamas presence in the West Bank and yet there Palestinians are routinely kicked out of their homes, beaten and shot by fanatical settlers as the Israeli army supervises. That is the reality of Israel. A fascist ethnostate, lawless and hyper aggressive. A Rhodesia on the Mediterranean if you will.
there was lovely border crossing with egypt. this is till hamas started to export terror to sinai and egypt build a wall on border with gaza. and another wall in last year. open air prison narrative is boring. 100k palestinians left gaza after oct 2023. prior to oct 7th there were videos talking about gaza as vacation destination.
there is significant hamas presence in west bank. in fact there are cities that PA can't go to. About half year-year ago PA tried to remove Hamas from Jenin but got it ass kicked and had to ask Israel to clean it from Hamas. In fact, PA still in "control" of areas A/B because Israel works on suppressing hamas and pij in west bank. Latest may polls show that hamas support in west bank is higher than for any other party (which is one of the reasons that PA doesn't hold elections in past 20 years).
Withdrawal from Gaza is very opinionated, some say it was to give Palestinians self rule as you say, many others see it as a tactical move making it an open air prison, and that Israel itself preferred that Hamas take over Gaza.
My only hope is that on both sides there are enough people that want to live in peace and prosperity with equal rights and care for each others regardless of their roots and don’t care if you call it Israel or Palestine or whatever.
Extremist groups in Israel came to life after second intifada and started as revenge groups, that performed same type of attacks that Palestinians performed on Israeli. You can say that they were radicalized by Palestinian violence (I think in your original post you were worried about results of radicalization as result of violence, didn't you ? Somehow people forget that it can go both ways). They also don't hold a candle to hamas/pij/pflp/etc and their actions way overreported and misreported [0] while other stuff is underreported [1]
Blockade of gaza mostly started in 2007 after palestinian elections of 2006 in which hamas won both in west bank and gaza (usa pushed to have election), failed coup (sponsored by usa) of PLO against hamas that resulted in hamas (internationally recognized terrorist organization). takeover of gaza in 2007. I want to remind that Israel disengaged from Gaza in 2005 and what followed are hundreds of rockets on Israel [2]

And the actions of Israel in the past 30 years, and affirmations from its leaders don’t seem to be moving toward the OSLO accords, otherwise why building all those settlements in the west-bank? It just doesn’t make sense.
anyway who cares about the past I am more interested in the future:
1) In your opinion how all this crisis could be solved?
2) If you had the misfortune of being born in Gaza, and obviously you cannot leave it, what would you do?
in past 30 years there were multiple attempts on behalf of Israel for agreements that were rejected by palestinians. and could you please count how many settlements were build by state since 2000 for example ?
1) hostages returned. hamas/pij/pflp disarm. gaza taken over by international force for purpose of stabilization and reconstruction. school curriculum is changed - both in gaza and west bank. deep reforms in PA (Emirati foreign minister then called the Palestinian leadership "Ali Baba and the forty thieves" and claimed senior officials in the Palestinian Authority are "useless" and therefore "replacing them with one another will only lead to the same result.").
2) 100k palestinians left gaza since oct 7th 2023. Israel said that it will help to leave gaza whoever wants to leave. But more to a point of your question - I'll hide/avoid area of hostilities.
