It really is a broad spectrum and it's quite possible to have both authoritarian ideals in one category while having libertarian values in a different category.

I do favor the simplicity of the political compass with four points. It has a specific name but I can't think of it at the moment. It is simplistic, and reductionist, but it is handy enough for a forum post and adequate for generalized conversations.

But, as you suggest, it's much more complicated than that. We humans really do like putting things into boxes, or so it seems.
