Linux user for 25-ish years here, and exclusively so.

I used to heavily configure my ubuntu distros to be keyboard exclusive with i3wm and such, but I ended up with regolith desktop, a version of ubuntu with pre installed i3wm and keyboard focus. I'm too old to keep my dotfiles updated.

Nowadays, imo you should only choose the package manager, any os using that chosen package manager (aptitude for ubuntu) definitely had a version that's close enough to your use cases.
