I agree with the others that testing in a VM (Virtual Machine) first is probably a good idea. Keep in mind that because of missing 3D acceleration inside a VM things like desktop animations might not work.
As for distros, I’d recommend Mint or Fedora. I personally use Fedora.
What’s also important is the desktop environment you choose. The most popular ones are GNOME and KDE Plasma. GNOME is closer to MacOS than Windows and is made to just work while KDE Plasma has a layout similar to Windows out of the box but is very customizable and has a lot of options. Ubuntu uses GNOME but they make quite a few changes to it. Fedora uses GNOME by default but there’s also a KDE Plasma version, I think. Mint doesn’t have these 2 by default, you can always install them if you want to afterwards tho. The 3 options Mint gives you are also more Windows-like but I haven’t tried them myself, so I can’t tell you much about them. A VM would give you the ability to just install them, try them out and delete them afterwards. I personally use GNOME btw.
