Unfortunately right now trial & error using testpmd is the most effective
approach to determine whether specific combinations are supported by any
given NIC.

Ideally doc/guides/nics/features.rst [1] should document each rte_flow
feature reflected in doc/guide/nics/features/*.ini for individual PMDs [2],
but that list is currently too incomplete to be useful.

Now to answer your question, although those are likely not the only ones, I
know from experience that both mlx4 and mlx5 support flow rules matching VID
+ dst MAC simultaneously.
