My condolences, the only thing Windows is actually needed for is playing games and thanks to Valve and SteamOS's work on Proton, Linux is a truly viable alternative now.
Generally specialist software for different industries will make you pick between Apple and Microsoft but I think that's a different beast because having a one-off (cracked) Windows box for say video editing meets the protest bar pretty well.
FFS: getting out of the Apple ecosystem is the easy part.
Avoiding the Windows ecosystem, for me, has been much harder. Generally, there is somebody that will incidentally pull you into it for work.
