Tbf, Unbuntu works, but they're ran by a company which has made some questionable choices. You can still go with it if you don't care too much, it has the advantages of being user friendly and well documented.
If you'd rather not, but you want something not too far and equally easy, you can go with Linux Mint, which is based on Ubuntu but disables snaps. They also offer differently choices of desktop environments, the default being Cinnamon (which looks a bit more like windows), and another being Mate, which is closer to Gnome.
They also have a "Debian Edition", which aims to stop being dependant on Ubuntu and may or may not replace the default edition someday, but so far it's not the one they recommend for new users.
I think they might've diverged from therians (placentals+ marsupials) before their ancestors became viviparous.
