content types vs. paragraphes types + taxonomy
Personally I don't think this is a good use case for paragraphs. I don't see any benefit of having only a single content (node) type, you are just moving comeplexity from nodes to paragraphs.

I think the key here is to carefully plan and reuse fields across entities. If your car equipment and your plane equipment both have a weight attribute, reuse the same field (or to be more precise: reuse the field storage), so e.g. you can use it to as filter in a shared view for both equipment types.
