Plus, movement - like everything else in D&D - is an abstraction. A character who doesn't move mechanically - who doesn't leave their square - isn't stock still. They move within the square, move limbs, dodge attacks, jockey for position, seek openings.Hovering, but not hovering as the ability.
If it pleases you, have the player say they are flying directly upward at the same speed that gravity is pulling them down. This seems like it would fit your requirements.
If saying this becomes tiring or drawn-out, let them hover.
I have no problem at all seeing an aaracockra maintaining altitude while not doing anything that game mechanics would call movement - or at least no more problem than I have with those wings producing enough lift to carry an even modestly geared-up human-sized adventurer airborne in the first place.
