Hi and welcome to Arturia forums.
You only have the resize options you mention. There is'nt any option that adapt to your screen like a full screen option. How would you have a fullscreen option if you wan't to keep dimension relationships and resolution the same at any size on any screen type - especially with GUI's that use bitmap images and not vector graphic? I guess it could be more background.
I find the chosen sizes annoying in my DAW Studio One 3 Pro, as the bottom panel that have functions disapear, when using a decent size even on a Full HD screen. Some applications don't show the bottom panel no matter the size. I would like that there was'nt any functions or displays in the bottom panel or something else that helps on this problem.
