The other main issue for me is dealing with moving or copying things around.

I don't think anyone needs to do a lot of file-management on the command-line. GUI file-managers are perfectly fine for home-directory stuff, USB-drives, network directories etc., but you'll run into problems when accessing system files. There's also TUI file managers like Midnight Commander which some would probably consider the best of both worlds. I personally prefer dired on Emacs (and Emacs in general to most terminal based applications).

As I said in the beginning of my comment, you can do 99% of your daily Linux desktop usage in the GUI, and you don't have to be used to or fast with the terminal. I just want new users to get rid of that fear, so that when they need to do something with it, they're not giving up or putting it of, but read and try their way through it and maybe learn something cool. Every Linux user (managing their own system) will need it once in a while and that's probably not going to change in the near future.

And a lot of common things can be printed/written on cheat sheets or getting stickers with common commands to put on the side of the case or stuck to a desk in easily glanced at locations.

I'm a developer and pretty experienced with the terminal, but I still do this. Not printed out or anything, but for each program with complex switches (like ffmpeg, qemu, docker, git, curl) I have an entry in my personal Wiki (also Emacs: org-roam) giving me a quicker overview over things I've already figured out in the past than a man-page can provide (it doesn't hurt though that Emacs has a pretty great man-page viewer too).
