Ubuntu 22.04 LTS will receive security updates until April 2027.
(So, if you're upgrading to new Ubuntu releases every six months, it sounds like that you're not following the upgrade strategy that would be suggested by your requirements.)

Ubuntu has a really persistent update mechaism built in.
Arch derived distos would be good, updates are only when you manually run them...
I use arch + fluxbox and I've been able to move my configuration from computer to computer by simply copying my home directory. When the new computer boots, I have the exact same desktop environment that I prefer. It only changes when I change it.
The OP doesn't object to updates, but to unexpected breaking changes, where th change is caused by different design decisions rather than bugs. LTS releases should not have those.
