My feeling is that might be a lack of choice here. So, just my 0.00002 cents, to supply you with a few more options:

• Just use Debian. It is boring but it will work.
• Or, Tumleweed has been named. But it is not maximally stable. Better, use Tumbleweed in a VM on top of OpenSuSE leap. That way, you have both superb stability and a very current system.
• You could also sell your nvidia card (let’s be honest, it probavly will only bring you grief), and get a AMD radeon which is fully supported by a libre kernel. Then, you can install Guix on it. Then you have a truly reproducible, very lean and organized system.
• If dropping the nvidia card sounds too extreme for you, you can also install Debian, and install Guix as a package manager on top of it. That will work because the Debian kernel supports the hardware. But don’t forget that NVidia is a nuisance, often. Well, you might have luck.
• Let’s say you are short on money and you don’t want a system that consumes too much RAM, since that has gotten expensive, man. So, you could get Debian with XFce as Desktop environment. Or, even leaner, you could get ICeWM.
• Or in case you want a very fast Lisp-based window manager with very fast, manual tiling, try StumpWM, say, on Debian.
• Or, if you want an automatic tiling WM, give i3wm or sway a try. Or GNOME with paperWM extension.
• GNOME would also run on Ubuntu, or on Mint. Actually, it is all Debian under the hood, mostly. Just easier to install.
• Or you want a privacy-focused Distro. Try Trisquel.
• Or, you just want to keep it simple, perhaps. In that case, I’d recommend Debian. Or, perhaps for the start, Debian-derived distro that is easy to install. There are plenty.
• But when you want to have it even simpler, get rid of the nvidia card. This really simplifies things.
