Long time system builder here. I would stick with an ASUS motherboard and Corsair for Ram and your Power supply. Intel or AMD is a toss-up but cooling is important and All in One watercooling systems are now inexpensive, easy to install and very reliable. Nvidia for your graphics.
For your O/S I would still go with Windows 11 for maximum compatibility for the programs you want to run as well as ease of use. There are hundreds of YouTube videos showing you how to do anything you might need to do as well as videos showing you how to streamline and remove unnecessary bloat. A couple hours of research and Windows 11 can be made to behave and run like a champ. Linux will require a lot more time to learn...
