The attractiveness of RSA_set0_key(rsa, n, NULL, NULL); is that you can
provide whatever many (from 1 to 3 :) parameters using the same single
function call, rather than learning three different (albeit quite simple
:) independent functions.

Yes, but this difference adds convenience, IMHO. My preference is this:
RSA_set0_key(rsa, n, e, d); with any parameter (except for rsa :)
potentially NULL.
