I've never been entirely surely of the value of "taxonomy" of this form because for me personally, it tells me next to nothing about whether I'll actually enjoy
For example, I like C.J. Cherryh's SF books very much indeed, and I don't think there would be any argument that books like "Downbelow Station" are "Hard SF". On the other hand, "Cyberpunk" as written by authors like William Gibson does nothing for me at all - I just don't enjoy him as an author, full stop.
