I really think you would have a great time with either "Linux Mint" because of its rocksolid philosophy of not breaking stuff or shipping "beta software".
Otherwise a safe option would be a Linux variant with professional support options - just in case you need it. ZorinOS, Tuxedo or Pop_OS! are the most common ones.
Personally i'd take Linux Mint, which in most cases works flawless out of the box. The premium options are nonetheless also great options.
Smart choice! The option to just try it in a safe way with the live USB is a good way to try it.
Also try out some of the themes in the settings π The amazing wallpapers of Linux Mint are so fancy, so I decided to use it on my work Windows PC, which I am forced to deal with βΊοΈ
