I definitely fall into the hyperphantasia category but my eyes have almost zero depth perception. Thus spatial relations is a nightmare for me and these 2D and 3D exercises were always my worst enemies. The only strategy I have is to try to use pictures in my head to move the objects but I can't do it quickly. I hated timed tests with any spatial relations testing. I agree that hyperphantasia is a bit of a curse. I saw a movie as a child about a rampaging grizzly bear (I still remember it was called Night of the Grizzly and I don't recommend it!) I vividly remember the movie now at age 63. I have learned to avoid horror movies and even scary cartoons.  So.... I wonder if hyperphantasia contributes to phobias? I bet it does!
