If NP-internal constituents agree in two categories these will most likely be number and gender or number and person, depending on whether the targets are modifiers/determiners (and the controllers head nouns) or head nouns (and the controllers attributive nouns). The second-most likely combination of two categories with modifier/determiner targets is that of number and case; and the only other permissible combination of two categories is that of gender and case.
