Nobarra, Bazzite, or CachyOS.

I'd say Nobara or Bazzite are better for 'I install it and it just works.'

Cachy is better for the learning aspect. It's not hard, but there are more choices to make, and you're closer to the Arch wiki and all its excellent resources/tutorials.

I am biased, as I run CachyOS and I love it. I also love how much stuff is in its repos, including everything you need to game optimally, and how easy CUDA is (which is part of what you need for CAD).

Whatever you choose, do not, I repeat DO NOT install Fedora, Debian, or anything that doesn't explicitly support Nvidia laptops by default, out of the box, or you are in for a world of pain. If any guide starts with 'install these 3rd party repos' or so, you have entered a danger zone, and you will hate linux.
