In spatial Intelligence, I would rather say that many trained designers have more than average spatial intelligence in Origami. Trained designers, I mean those that are well trained in spatial thinking such as engineers, physicist, chemists, mathematicians, and lots more are more than active when it comes spatial intelligence. In addition, I'll rather say that I've seen a professional sculptor who later came to joined Origami in his career.

I can't really say that good spatial intelligence is needed for origami folding. So, I think with patience, good eyes for details, and ability to follow directions are enough for you to enjoy Origami. I consider myself an average folder due to the fact that I don't see things in 3D (probably a good point why I can't fold CPs). To sum it up, Lack of origami dexterity and patience have one way or the other hinder me from being able to fold many complex models. Even if my spatial intelligence is on the high side, I would still not enjoy folding for hours. That's personal though.
