Nothing wrong with Ubuntu, but it's interface is definitely geared more towards Mac folks.
My recommendation for someone making the jump to full time Linux is Fedora Kinoite. It's "immutable" meaning impossible to break, and uses KDE Plasma, which is like the modern Windows you've always wanted.
Again nothing wrong with Ubuntu, it's great and will run on the hardware you mentioned, but if you are someone who wants to tweak settings without fear of breaking something somewhere else, I really recommend Kinoite.

I expected lols I did not expect to perpetuate a nearly 50 year old debate
