I never felt comfortable managing openbsd, but linux has repeatedly and gratuitously changed all the management tools, so now it’s easier for me to get around an openbsd box, despite using Linux daily, and openbsd maybe twice a year.
(It’s a serious question. I’m strongly considering switching to one of the bsd’s at this point.)
Are you not so subtly referring to the systemd fiasco? That was about, if not over 10 years ago. I also don't think it matters. Change is not a bad thing, and that change is not as hectic or constant as you seem to imply.
If you really want a Linux distro that hasn't changed at all in the past 30 years, Slackware might be your bets bet, but I don't think that 'having not changed in the past 30 years' really makes sense as a metric.
Personally, I'm a fan of Alpine and Void Linux, and I also run NetBSD. FreeBSD seems too 'messy' as someone that likes minimalism, and OpenBSD's security focus is misplaced IMO.
Wayland, ACLs, SELinux and cgroup are all just options, none are forced.
Was deprecated ~20 years ago. Not a recent change.

This doesn't make any sense? It's like writing "network drivers vs. X11" in OpenBSD.
The best thing about it is that it is boring, completely predictable outside of hardware faults, and dependable. If you know how to competently manage it, which isn't hard, it is a rock.
Also nice is that FreeBSD isn't involved in vendor tugs-of-war that result in the constant stream of bullshit changes* - the network config format doesn't change every version, people aren't playing political games with init, etc. All of which mean far fewer goofy make-work surprises.
And the quality of their releases is still very high. I consider them one of top open source projects, period, in terms of qualities others should emulate for better results.
As with anything, it isn't for everything. If you need the latest version of whatever is trendy this month, you should run Linux. But if your use case benefits from stability and ease of administration, FreeBSD rocks.
