Thinking nothing more wonky than mint/pop!/bazzite/elementary. I know there is never “one” perfect one but feeling like trying something new on this machine that’s at least somewhat push button. 
Since it no longer receive regular updates from Apple I just want to keep this machine available for use when needed.

I’m pretty comfortable on the above ones I mentioned. I’m not a coder/engineer so I tend to lean heavily on flatpaks and such, though if I have to go into the terminal occasionally I can usually poke my way around
