I'd recommend against Ubuntu. It uses snaps and it'll teach you that the hard way eventually by having very weird issues.
Mint is based on ubuntu but says no to snaps, so that's a good place to start.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Debian with GNOME
I'd agree with the choice of Debian (or a derivation as LMDE, *buntu, Linux Mint, ...), but would suggest KDE. Anyway, I think a beginner should try the distro of their choice on a live medium first to get in touch with the look and feel of the desktop environment.
Linux Mint or Garuda Linux
I still think Ubuntu or a flavor of it is the right answer for people new to Linux.
If by flavor you mean linux mint: yes, absolutely! If you mean anything else thats more like ubuntu itself: hell no!
Do yourself a favor and just go with Debian Stable
Wanted to write the same. Normaly I would suggest Mint, but OP sounds like they are ready to learn and endure some things to end up very happy with Debian, the mother of all distros.
I know of Arch wiki, but are there wiki's explaining easier distros? I'm on Nobara, because I want to game, but perhaps I could be learning to configure and install some of these tools to be able to one day use any distro for whatever I wanna do?
When I started with Debian I found everything I wanted to know with Duckduckgo... "Linux Debian how to..." without exception. And sometimes even the Archwiki helped me. You don't need a single place with all the knowledge, you just have to practice how to break down your questions into easy to answer bits. Doesn't matter which distro you use.
Do you got NVIDIA?
