Too bad your question requires no pawns before I can apply my new endgame tablebases to it (limit is 6 pieces, including kings of course).

Without pawns it would not be an interesting question.
However,...

I recently sparred against Fritz from a legal pawnless position where each color had all of its officers except a B or N.

Fritz showed me there is a whole world of chess tactics that I had never personally experienced nor even seen before. After a few brief turns I was already lacking mobility due to threats and the burden of defense.

There might not even be anything 'real' here (I don't know). The bishop pair is hugely better when there's action on two sides/ideally outside passed pawn(s) and d4 is a very nice outpost of course.

Not that that's relevant, as you're playing practical chess One of the nice things about 'seeing what white does' is that they've got to find sane moves to play!

Get, and keep, someone in a relatively passive position and it gets incredibly hard for them to do, and keep doing, that. If nothing else it simply isn't any fun.

Not at all sure you ever want to strand that bishop on b2. Keep the threat of going in there alive, yes, but also keep it flexible to help on the kingside? More for white to worry about.

I haven't engine checked the game or anything but I'd imagine grabbing as much space as possible on the kingside would be key to converting Black's advantage in an actual game. So I would play ...f5, ...g5, ...h5 and ...f4 and try to create additional weaknesses. In such positions it doesn't really help to approach the position from the perspective of 'how do I win' - the emphasis should be on accumulating and transforming advantages and calculating thoroughly when the position takes on a more concrete character.
