I recommend Fedora. It's rock solid while also having really up-to-date packages coming often. Not bleeding edge but deffo leading edge. Also has a decent amount of info online when you hit an issue.
I used to use Ubuntu but the older packages, and Canonical with their obsession with SNAP and becoming a baby Microsoft kept me away.
Arch is a good option and TONS of information online for help (some of the best) but it is a bit more DIY and is a rolling release so very up-to-date package but keep clear of Manjaro, just do base Arch. The folk managing it keep dropping the ball so not worth the headache
Plex is great if you want to pay for features and need a media server/streaming platform hybrid
