As also stated by others you should start learning the basic concepts and no specific flavor/distro to understand how everything fits together. You sound like someone who could very well succeed in that, since you didn't give up yet :)

I can only recommend starting to read https://wiki.archlinux.org/title/Installation_guide

Once I installed arch I never looked back. I heard good things of the rolling distros of Suse and Fedora as well, but arch feels more vanilla than the others to me.

If you have a lot of time and passion you could also have a run of linux from scratch. You do it once for the learning part and then choose a distro of your liking.
