At this point, I am afraid that you will never be able to switch to Linux completely. You know what they say, can't teach old dog new tricks. Linux has it's issues and Windows also has it's own issues. You have to choose which ones you can live with one you cannot.

For me, I use a FHD display where 100% scaling looks the best and also it's the small things I cannot live without, like Super+drag to drag/scale windows from anywhere, middle-click paste, powerful POSIX shells (yes, yes I know PowerShell, too old to learn a new shell), etc. But I cannot live with Windows privacy nightmare, mouse-heavy desktop environment.

Just do use what you like. Just have fun computing.
