Presumably the predominant portion of the energy used to raise an elevator is for the mass of the elevator itself

Usually elevators are counterweighted fairly significantly.

As you say it is actually using very little energy in overcoming the inertia of the system to go up as the counterweight outweighs an empty elevator, and the weight of a drone is insignificant in this regard. However when coming back down the system must raise the heavy counterweight which is only partially balanced by the empty elevator.
