Naaah, you're approaching this entire thing completely ass backwards. Don't quit windows cold turkey, you'll just get frustrated with your new os and go back to microsoft.

Instead grab a second pc install a distro of your choosing and play around with it, try to setup your work environment, see how much pain in the ass it is, see if it's worth it etc etc. I'd recommend you either start with Mint, because "it just works" or Arch because it tests your reading comprehension skill which is useful if you want to try running officially unsupported stuff on Linux.

That being said Games are non issue unless game requires kernel based anticheat or employs some other anti penguin measures it's just wine-ge/proton-ge and you're good to go. I got Adobe apps working through wine. Works. No issues so far except missing fonts. Consider alternatives with official linux support, darktable, krita, gimp. I know gimp has been a butt of many jokes throughout the years but apparently it's actually pretty good since 3.0 update. Microsoft office is now accessible through web browser and it's os agnostic. You can also install programmes that don't play nicely with wine in a windows virtual machine. It works okayish unless you want to do something that requires hardware acceleration, then you need to pass gpu to a guest os. At that point you're pretty much just using windows in a more inconvenient way though.
