The Golden Eagle was a go around prop strike under power.
Sadly a piece of the prop entered the cockpit killing one of the occupants. Nevertheless it shows that there is a lot more energy to do damage if the prop is under power on striking.
Most gear up prop strikes are due to gear failure.In such an event burning off fuel is sensible hence a diversion to a large runway with good emergency services and preferably foam to avoid spark fuel ignition is also sensible.
As such landing short would not be a problem to an experienced pilot.
Cutting the engines at 50 feet when landing is assured would be far safer than landing under power.
One pilot flew over a van with an engineer on the back who pulled the one undercarriage leg down and there are other examples of creative piloting.
I don't consider much risk on cutting the engines unless a poor pilot is at the controls
