My go-to advise for people new to linux or just wanting something that works is Linux Mint (Or Ubuntu if you don't mind the commercial aftertaste). End of discussion.

It is based on Ubuntu packages which are well maintained (things just work), it has been around and popular for a very long time, has a big and active community, and it prioritises ease of use.

The only downsides are support for brand new hardware (<6-12 months) which takes a while to be supported. But that doesn't seem to apply to you.

If you want bleeding edge, extensive customizations, or a cool unconventional desktop you can check out any kind of desktop.

I like discussing distros as much as the next person. But in my long distrohopping career I realised that with new or novice linux users it's best to stick to the easiest, most out of the box experience. I would argue this is linux mint.

I've seen too many times that people send new linux users to the most wild distro's and then be suprised that the user gives up on linux completely after a week.

If you want to get some terminal/technical experience or like to make your hands dirty feel free to experiment.
But make your feet wet in the shallow well known puddles.
