Mint is the most mentioned choice and an extremely great beginner distro with an huge community.
ZorinOS will get a big update very soon and is also a very good choice. It was my first distro, especially because it looks very modern and pleasing.
If you’re a tiny bit more advanced and get the basics, then you might take a look at the immutable Fedora variants like Silverblue.
They have many advantages compared to traditional distros like the two mentioned above, but atomic Linux is a relatively new concept. I also find them easier to understand and use, and, imo, they’re even more user friendly, but not as refined.
