Distro doesn't really matter. I guess arch will force you to use it more than any other distro, at least in the beginning. (Thoughbeit you can avoid the commandline almost entirely by using archinstall to immediately install graphical programs for everything like package management).
I do recommend the program/command tldr (github.com/tldr-pages/tldr). There's lots of different clients out there, some can be really slow. I personally use tealdeer which is instant.
>>20098 NTA but DE stands for Desktop Environment (
https://wiki.archlinux.org/title/Desktop_environment). I'm assuming
>>20096 is referring to the fact that most DE's login screens (AKA display manager/DM) don't let you log in as root (meaning you'd launch every program as root by default, all shells would be root shells, and you'd never have to put in the root password after logging in). This can be changed, naturally, though is inadvisable. See
