All your points seems like they are trivially solved by using another DE and distribution
(fwiw: my propensity for installing new DEs and distros in the hope of solving all my problems was what made me leave linux in the first place)
They're all there, just a few clicks away in whatever crap-ass GUI Ubuntu has stuck on top of apt these days. At the end of the day, all these distros are just Debian, Redhat, or (rarely) Arch under the hood, so if you get sick of lack of support for JimBobLinux, you can just install Debian and quit fucking around. I did that 15 years ago (good god) and haven't regretted it.
