I think it boils down to trade offs.

The major benefit to Wayland is that it has less overhead since apps talk directly to the desktop. Having desktops implement the protocols instead of relying on a external project means that the user experience is cleaner.

For smaller projects like window managers there are libraries that implement the core protocols. This allows for the minimal window managers Linux traditionally had as an option.

I won't argue that Wayland has issues with remote desktop. The problem currently is that it has to be implemented as a custom non standardized solution by every desktop. I don't think that there are any portals for doing session management which is unfortunate.

From a accessibility perspective I believe that has already been addressed.

I also don't see any reason to try to "market" Linux. Windows 11 is the successor to Windows 10. It isn't that bad compared to ever other version of Windows.
