Depends. Whatever choice you pick - go with Plasma (KDE) desktop. Most of below choices have alternative desktop flavors that offer Plasma instead of Gnome.

If your goal is to play games - something like Bazzite might work.

If your goal is to have a desktop experience with some gaming, something like NobaraOS or PopOS would work.

If your goal is only desktop experience - ubuntu will work.

If your goal is to learn and have super awesome Linux desktop - Arch Linux.

Personally I am in Arch Linux for the past decade. Tried many different ones and Arch Linux is the only one that simply "just works" for me. Not suitable for beginners.

I use Fedora Silverblue personally (feels rock-solid and borderline impossible to mess up), but you might want to get more familiar with the basics before getting into immutable distros. I'd echo what everyone else is saying and do Linux Mint first

I plan to do the same. Since all I do on my PC is play Steam games, I was thinking of going to SteamOS. No idea if that's even a good idea though.

Do it now

Mint 💯

Zero experience = ignore standard Distributions

Fedora Kinoite from ublue.it

So much stability and reliability, while modern packages. Just using Debian or Mint (Ubuntu LTS with an outdated Desktop and opinionated theming) is not a solution for a good experience, as you need updates.

Btw I broke every other Distro before, so I ended up on Fedora Kinoite

version 6.6.10 is not bad, working great for me

Steam os

Fedora Silverblue if your wanting security and a "it just works" experience.

Linux Mint Debian Edition if you want stability and a traditional/familiar environment.

Vanilla OS Orchid should be a nice in-between once it releases.

Kde plasma if you game
