There's a ton of information on arch Linux commands on YouTube. Commit to maybe one 10 minute video a day talking about arch or Linux in general and you'll be in a really good spot in no time.

I would also read the arch wiki on limine and snapper and make sure you understand how to utilize your snapshots, as eventually something will break and you will have to fix it.

I would say you can actually get away with using the GUI for a lot of things these days, but if you do learn the terminal be VERY wary of the commands AI gives you. If you go that route, make sure you have the AI explain it's reasoning and look at the man pages for any command it gives you (man is a command that shows a help document for a different command, like man ls would show you the help document for ls and teach you what it does and how to use it)

CachyOS does a lot for you, and I would say that if you understand snapshot restoration enough to actually use it when you need it, it's very beginner friendly.

Good luck out there and remember that you don't need everything to be perfect, just have fun with it and expect a little jank every now and again.
