Debian in particular is rock solid, even Debian Unstable has been very reliable for me if you want a rolling release with newer packages.
But I’ve also had very few problems with Ubuntu. My mother has used it for ten years at this point and will happily apply any dist upgrade she’s presented with, and rarely does she need support.
A pro tip is to check out the alternative desktop environments. A lot of people rightly hate Ubuntu’s awful default DE, but it’s not a core part of the distro, there are other complete desktop “flavours” available in the repositories and installers that will give you them from the start at https://ubuntu.com/desktop/flavours
(Switching an installed system from one DE to another is in principle as easy as uninstalling one desktop meta-package and installing another, but you got to make sure you get the right packages, or you might run into annoying conflicts, so I would not recommend it for a newbie)
