Will FieldFox instruments be able to differentiate between internal and external zeroing when using the U200xA/B/H USB power sensors?

FieldFox instruments cannot do this differentiation, but FieldFox allows you the choice of external zeroing. The default is internal zeroing. This is how the USB power sensors operate. If you measuring power levels below -30 dBm, Keysight recommends an external zeroing be performed. There is an external zeroing soft key on FieldFox that can be pressed.
