honestly most distros will be fine. what matters more is your desktop environment. pick something light where Bells and whistles can be turned off. i used fvwm for many years on a lower spec system. now I use kde/plasma on wayland.
I’ve used arch and Debian on low spec systems. both were fine. slightly prefer arch cause it’s more up to date
lol. i used Gentoo for 5 years or so. it’s the only distribution I don’t recommend.
it assumes you have hours of CPU time to waste, and hours of your time to
dispatch-config
afterwords.do Debian or arch.
