The self-hosted and home-automation and home-assistant subreddits are _full_ of discussion threads on this. The good news is that you have a TON of options to pick from. The bad news is that they're all deficient in one way or another so you really do have to spend a bit of time to figure out who executes best on the things you care most about.
If you don't mind the lock-in, Unifi is nice. Reolink (and the other DaHua re-brands) usually leave a lot to be desired in terms of software / quality but they are cheap and they reliably spit out a regular video stream that can be used with just about any software. Just don't let them onto the WAN!
Alternatives really need to be for the masses that have little Knowles in server hosting.
This is one reason I invest in Linux Smartphone company's that are work towards a clean solution for the masses. Daily drivers that are satisfactory for us build the stepping stones to walk to the alternative.

I dont understand why anyone chooses Ring when the costs of Unifi are so much better.
The ring app also sucks imo and all their hardware is quite slow.
All tech puts it's best foot forward, some of it's really nifty, but a camera on every street corner is always going to pose more risks than it's worth IMO...
It's work to go back to the old ways but I think this is one we step we should really all take.
Truly top-notch quality, full-featured, very low maintenance, easy to set up, cheap to operate. I'm glad so many people are using it now.
For video doorbell I just have a cam that can see the front door and I drew a box around the area I want notifications for. When a person enters the box, I get a notification and snapshot.
I made it half a century without a doorbell in my phone. I don't need it now.
Unfortunately a portion of the information getting circulated is the complete opposite.
You certainly can't be sure of that. In fact, it is almost certain that these companies provide the data they collect to the police and government agencies data, often without warrant.
I'm not an asshole so I cancelled my subscription.
If other people are cool with doing things without any reasons and based on pure trust, that's on them. But that's not gonna be me
Consider the Nancy Guthrie case. The owner wasn't around to give consent, and the camera didn't even have an active subscription, yet law enforcement was still able to recover video from Google's systems.
The only way it could be as you say is if the video was only stored locally without any remote access, or if the video was encrypted with keys only you control. Google clearly is not doing this. I really, really doubt Amazon is.
