“What does M$ Windows provide to me as a computer user that I can’t get elsewhere?”
Proper low blue light adjustments for using my PC at night. Windows 11 has this and it works great.
low blue light = red shift ..... Your display is now more red oriented and lot less blue light. I am using this right this moment! For my 27” LED display.

System>>>

Night Light .... and adjust
Linux has an application that has been around forever called exactly that, “Redshift” and it does exactly the same.
