XFCE ist really nice. It comes with different presets and can be made to cater to ones preferences rather easily.

It is the default of xubuntu, which imho is a good first desktop linux, mostly because of the extensive documentation and tutorials for it.

There is also Linux Mint XFCE. I prefer this because *ubuntu isn't focused on the desktop any more and Mint is. Also, Snaps are annoying and he repo is controlled by Canonical. Mint doesn't have Snaps unless you want them.
