Sorry but, your list of examples feels like a list produced by an AI from a set of articles about aphantasia, or it's like you're too influenced by these articles. Rotating 3d objects, doing multiple visual operations on a rubik's cube or mental abacus are not operations that even people with hyperphantasia will be able to do naturaly. If you gave more examples of every day situations, or if you told us that you tried to train for thoses operations for 3 months and failed, we could conclude something else.
