The main alternative to LVGL seems to be TouchGFX[1], at least that's the one I've seen mentioned the most in conversations around UI libraries for microcontrollers.

As you wrote these aren't made for desktop apps, but you can use desktop apps to help with UI development using these libraries.

For LVGL there's SquareLine Studio[2], I used it a few years ago and it was helpful. For TouchGFX there's TouchGFXDesigner[3], I haven't used it myself and it seems to run only on Windows.
