I am a gui only user. AMA. I have to use command line occasionally but it's less than once a month, if that. Im on EndeavourOS desktop for over 2 years with Bauh managing updates. My home server runs Unraid with a web GUI interface maybe used CLI twice in 5 years? They told me Linux could be what I wanted it to be. I don't want to use command line, so I don't!
I find the documentation to be very good for Arch based distros. The EOS forums or Archlinux.org wiki almost always has what I need. Otherwise the github page usually has Arch install directions that are very clear. The major things I've had to do in terminal is just initial set up of applications, enabling things to run on startup or changing configs. For example, and this is the most complicated example I can think of. I use grub-btrfs to put my Timeshift snapshots into the grub menu. All I really had to do was 3 commands:
sudo systemctl start grub-btrfsd
sudo systemctl enable grub-btrfsd
sudo systemctl edit --full grub-btrfsd
The first two commands start the daemon and set it to run on start up, the 3rd command is editing the config so I could use Timeshift over Snapper. Again this is the most complicated example I can think of and its 3 lines. Not only that but I was able to find documentation on two different sites. In under a minute of googling.
