>>On my Win10 22H2 system Firefox and File Explorer maximized windows can be dragged, but while being dragged they automatically reduce to the most recent non-maximized size.
>>They can then be "thrown" to another monitor and will restore to full screen size, but if just dragged to another monitor, will remain at the non-maximized size.

>That's the behaviour I see, and expect. The real fancy thing is that VFP does not, because it is a windows thing. Looks like VFP (and VFPA) is handling (or not handling) a click move - iow a drag - of itself the wrong way. Sometimes it's just old. ¯\_(ツ)_/¯

On my system it's controlled by Settings...System...Multitasking...Snap windows. If enabled, maximized windows can be dragged. If disabled, they cannot. (tested only with Firefox)
