Also I think at the core of the "visualizing things in different parts of space" memory trick is just making good associations. If you're much better at verbal/internal monologue type of thinking you could still do something pretty similar, by mapping the things to memorize into a story.

Granted certain things are easier to map to a visual space than to language, but that's true in the other direction too. Anecdotally it takes a lot of effort for me to visualize things and I barely do it naturally, but I seem to have a much stronger internal monologue and a better memory for things people say than most of my friends. I wouldn't be surprised if poor visualizing abilities during development could strengthen verbal reasoning a bit like how blind people have other senses heightened.

I really hope research into aphantasia will become more commonplace, but a lot of it is speculation for now unfortunately.
