Windows 11 is Windows 11 - no matter what flavor (S mode, Home, or Pro). If you saw that the Surface Go 1 Gen was not on the list, ALL 1st Gen models of the Surface Go 1st Gen will NOT install Windows 11.
You may see some 'hacks' out there to get Windows 11 to run on earlier model machines but those people will get a surprise sometime in the future.
Just leave your machine as it is, there is nothing wrong with Windows 10. The machine will fail before Windows 10 loses support.
