Thanks; I (too) briefly tried imagining other categories, but was quite happy with those four!
Regarding the first distinction, there is this recent (free) book that argues for the possibility of better politics by more strongly keeping normative and empirical assumptions separate from each other (which is called “the two-step ideal” in Chapter 1, pp. 9–17). I read the book twice and found it very illuminating on that distinction. Note that the book itself takes no normative step until Chapter 7, so it’s not all about reducing suffering.
