+1 for debian.
No need to mess around with debian derivatives for whatever pointless extra widgets they have.
It's good enough for most stuff and has "allow nonfree drivers" choice which helps with annoying hardware problems of the past.
If you don't care about desktop env, you probably don't care about wayland vs xorg either.
So I'd try XFCE, simple, basic, lightweight, fast, probably not the most modern or flashy,
but you're getting to work faster.
Is it that wierd little box thing that you have to take out of your smoke alarm to stop it beeping?
