I personally think shove should just make a target trip and go prone with like 1-2m distance. Seeing characters in full metal plate being sent flying is comical, so I think such physics should rather remain for spells and abilities with power. Such as Lae'zel's Pushing Attack or some spells such as Thunderwave.
But definitely not as a cheap and brainless one click button that can one shot any enemy just because of gravity.
