While I agree with this video. As someone who did migrate from Windows to Linux, I feel the biggest issue which wasn't address here was the planning for migrating to Linux.
Migrating to Linux means loosing access to Windows native applications like Adobe and ~~kernel level anti cheat~~ online games. What I found helped the most was transitioning to cross platform application and learning their ins and outs in Windows, or discovering ways to validate which applications work well in Proton and Wine.
With games ProtonDB is your best bet to see if there are issues. Or finding ways to solve issues.
With Professional software... you're not going to be as lucky, so transitioning to an alternative which works for you might be the best solution.
The best way to check if Linux will work for you is to run Linux in a VM or on an external SSD on your actual hardware. The best way to check if something works for you is to try it yourself.
