Hey, welcome, fellow noob!
I hopped on the Linux train maybe 20 years ago and haven’t had any non unix system in maybe 15 years.
Also, I don’t know anything much. I can do basic tasks with a Terminal, but I don’t think for example I could install Arch from scratch. Or if I’d accidentally opened VIM, I’d have to kill power to get out again. But I like to tinker. If you like to tinker it’s a big plus, otherwise things, that don’t work instantly, might get frustrating.
As others said, use a pre built distro + DE environment, especially if you don’t really know what you do. Another thing that I’d recommend: a distro that be backed up easily. So you can tinker and start over, if necessary.
If I don’t know, how to fix a thing, I usually look up my question online. The problem with that is: I’ll find solutions containing commands that I don’t know, what they do. I have “fixed” my OS to death before, so it’s always nice to have a recent backup.
Ubuntu is the biggest, although it’s not old-school like win98 and comes with idealistic problems for many people. If you didn’t really enjoy it, I wouldn’t go back, just because it has the biggest community. Community isn’t only about size.
Mint is rock solid, I’ve run that a long time with different DEs.
Another distro, I can’t really recommend (as I haven’t used it further than live USB yet), but might be very interesting for you, is MX Linux. It comes with simple DEs and more importantly: a ton of GUI tools (including a back up tool where you can back up the entire OS including apps and settings as a flash USB).
I don’t know, if I was able to help anything. I just wanted to reassure, that there are (maybe even many) Linux users that don’t really know what they do.
As with many skills in life, I believe, the best way to learn is by just doing it. There will be failures. And each failure is a big opportunity to learn something.
Emphasize on “should”? Thank you! I’ve looked this up several times just to have in forgotten when needed. So for me, VIM only, when I have internet access.
