Eh, Ubuntu used to be a decent desktop distro, but they've made some… choices. You can do better. Mint gets recommended a lot, but that also feels dated. It depends on what your use case is. GNOME vs KDE is a lot more important, find the one that you like better because that's how you'll be interacting with it all day. KDE is more like Windows, GNOME has a more Mac feel.

If you don't want to tinker with it, you just want it to work and want to use your apps as is, go with an immutable distro (e.g., Bazzite like OP suggested). You can't easily mess up the important bits that keep it running and as long as you reboot it from time to time you'll always have the latest updates. IMO, unless you actively want to mess with the underpinnings of your system, an immutable is the best way to go.

Bazzite is gaming focused, but if you're not a gamer, there are others (e.g., Kinoite). But in my experience, they just work leaving you to do what you actually want to do, not fight with it to make it work.
