This is quite a rabbit hole you are getting yourself into, but to keep it short and relatively simple, you need to figure out something very important beforehand:
Do you want a rolling release or a stable distro?
I'm assuming that, you are not yet familiar with these terms, so let's go with the stable distros.
You have a lot of options here, most of them will all be based of Ubuntu, which is based in Debian, so let me drop a few generally good suggestions in no particular order:
Linux Mint
MX Linux
ZorinOS
PopOS
Fedora, (This one is not a stable distro, but you should be good with it)
Either of these is a good starting point. If down the road you feel like they stop fitting your needs, start exploring the big three, (Debian, Fedora and Arch Linux).
