Well, the ZF is a good jack point. It will hold the load the of the engine and and ransaxle. For what you are contemplating it is a minimal load on the engine and transaxle.
But my vote is to pull the engine and transaxle as a unit. It will preserve the car's infrastructure. Doing so willl make it easy to clean the engine bay. Maybe replace the oil pan. It looks like someone used it as a jack point or rested the engine on the ground.
