Void Linux is what I use and it's by far my favourite, can't recommend it enough. It's rolling release while also being very stable, has a small but very engaged and welcoming community.

One I haven't seen here is Arco Linux. It's designed as a kind of learning path from getting to know basic Linux concepts to being able to install Arch on your own, so I think it's a pretty good early choice, tho probably not that good for the first choice.
General recommendation is that you choose something with good community support or at least good documentation. You might also not want a rolling release, because they tend to be more on the unstable side.
I know this thread is old, but let me add this to the conversation: Look into distrobox, it essentially allows you to use packages from any distro inside of your current one.
Warning: not space efficient
That said, this takes the question of "what packages do I want" out of the equation when choosing a distro
Thanks for the suggestion, I decided to give EndeavourOS a try and so far I'm really happy with it.
If you aren't familiar with Linux yet at all I would suggest a Mint. You can think about using stuff like Nix after you're a but not familiar with the way Unix-likes work.
I'm a bit familiar with Linux, but not that familiar I would be able to use Arch straight from the get-go.
I'd recommend Mint with XFCE. Stable, fast, simple and won't get in your way. Think of it as a more user friendly Debian, as Mint lets you install non-free drivers (nvidia) and codecs from the get-go
Dunno whether it'll play LoL well, most anti-cheat software hate Linux, but it might be worth a shot.
After having tried many distros, I settled on Fedora. It's a boring choice, but it has been a great experience for me. Everything pretty much works without issue, and the OS gets out of the way for me to do my work.
I also think that having a trustworthy company and team behind it matters. It's hard to trust some obscure distro to provide proper support, security updates, and proper testing.
Also, while I enjoy tinkering and messing around, my main OS is not one of the thinks I would want to tinker with. I have work to do, and I need a stable platform i can rely on.
If you are beginning I usually just point to Mint or Ubuntu. They do a lot for you so it's very easy to learn. Manjaro is also a more automated Arch and is the distro I prefer. But it still requires more familiarity with unix.
