We might be safer in terms of vulnerabilities, root exploits, RCEs, etc. but the internet is still full of malware, scams are still just as rampant. Vigilance is still very much required, but is no longer taught.
Look at all the malware available on the Play Store. The curation does nothing but create an illusion of safety.
Hell, cellphones these days ship with spyware pre-installed. Samsung being the one of the worst for filling their phones with their own apps which spy on you constantly.
Believing you are more under threat from sophisticated government hackers rather than unsecured IOT devices, unvetted npm packages or hijacked download links is just LARPing for people who want to sound more important than they actually are IMO.
This accounted for most of the risks on the wild west internet, but the worst case scenario of permanently losing data or having to reinstall Windows was actually rarer than it was made out to be imho.
These days the common risks are the same, except they're no longer risks - all of those have been built into the fabric of everyday internet usage and criminals have been replaced by businesses. It's like the cliche about Vegas being better when it was run by the mob.
That stuff is still there if you look for it, but it's not on your social media feeds or in any of the apps provided through app stores.
When I got filtering on observe-only mode I saw users were getting up to a dozen phishing emails every day.
We quickly did a hard simulated phishing test and most users opened the email but zero users clicked through.
Two years later, after we had excellent email filtering in place, our simulated phishing test had a 30% fail rate.
Take from that what you will!
In terms of cybersecurity, I see it as "security first" culture means people rely on the system to keep them safe. "Safety third" (or security third) emphasizes that everyone should already know they are operating in a risky and dangerous environment and take security as a personal responsibility.
It's just a reminder that no one cares about your life more than you do, so stay vigilant and take personal responsibility.
edit just realized I didn't actually answer your question on the first and second priorities.
I suppose First would be the reason the system exists in the first place (buy something online, for example). Second would be the user experience of doing the thing. Security should help you take calculated risks rather than prevent you from taking any risks at all.
