Let me warn you first, your GPU might cause some issues with the distro.

Based on all the info you told me about the distro you want, I would recommend Opensuse Tumbleweed.

After installing you would just need to install Nvidia drivers and the codecs and you will be ready to go.

If you plan to use flatpacks for your media playing software and browser then you won’t need codecs as it’s included in the flatpacks.

Just don’t forget to configure auto update and when you start installing at the final screen before clicking install make sure that ssh is disabled and selinux is enabled for extra security.

Extra notes:

• The default browser is firefox, but it can be replaced with any other browser.

• If you want a working office suite and you don’t have high requirements, you can choose between Libre Office, Free office[Prop] or WPS office [Prop].

I hope you enjoy your time on linux.
