Not who you asked, but also have aphantasia.

"think of" is far too ambiguous here to really meaningfully drill into the differences of _how_ people think about things. I know that a stop sign is a red octagon (with a white boundary) with the word "STOP" in the center. I could draw you a plausible picture of one without issue. Thinking about it just involves no imagery.

Information you might rely on visualization for, I don't (because I can't). I couldn't tell you with any confidence what my family that just visited this afternoon was wearing (something I assume is easier for people who would remember it visually), but I can recall what happened - in what order, where, who said what, etc. - throughout their visit.

I have a vivid imagination. My stop sign visualized as looking up to your right at a stop sign a few feet above your head, so a proportionally distorted octagon. The coating is metallic red and near-white and has a mild flaky look to it as some colored metal has, with a hint of rainbow from the sun that lights it from my back. There is a standard metal post with holes in it. There is a mostly blue sky as background framed with small leaved, large trees. I know that if I paned down, I'd see grass with small, yellow flowers.

When I lose my wife at the store, I often realize I would be useless in describing what she was wearing if I had to. If friends were over, I wont recall their attire unless it specifically came up, then I might remember it for years.
