I doubt that changing to Fusion Pro will resolve the screen resolution issue that you have. Both Fusion and Fusion Pro would be using the same virtual graphics driver inside the Windows 10 VM and using the same underlying macOS display and hardware.
What is the maximum resolution you see available in the Windows 10 VM?
What is the display preferences of the macOS?
