If you are familiar with Ubuntu still I recommend you fallback to that or if you hate canonical and telemetry then use mint. Honestly bro it depends on what you wanna use it for.
Generally:
Noobs -> popos, Ubuntu, mint, Devs -> fedora, Ubuntu (ease of access), debian Power users -> Arch, Nix, tails, (a bunch of other distros ig since any distro can be used in a powerful way tbh) Neckbeard -> Gentoo, LFS (not really a distro tho but amazing for learning)
But seriously speaking it's your choice bud. All Linux distros work amazing and are all the same to the kernel. You can always install multiple distros on an ext. SSD if you can't decide.
