I'll recommend NobaraOS. It comes with everything set up out-of-the box and you can change interface to Windows or macOS style.
DO NOT SWITCH, until you've found that every software you use has a Linux version... Or an alternative which works on Linux as well as for you.
ALSO DO NOT SWITCH if you have the 30 or 40 series NVIDIA cards. Or any NVIDIA card for that matter.
YouTube channel recommendations - The Linux Experiment, Tech Hut, Gardiner Bryant (old videos, he just makes Steam Deck content now)
Or Mull if you're on Android
