I really think black is lost in all lines against best play by white after 3 ... h6. 4 d4 is the most principled move. No particular point in 4 castles so far as I can see, except maybe to tempt black into a weak move. Maybe d6 would be weak, not sure.
- I agree with the first part of your post, that d4 is the best move, but your "except maybe to tempt black into a weak move. Maybe d6 would be weak, not sure."
I don't think black should play 5...Nxd4 because it just helps white's development advantage.
Bc5 for example should be better.
I know you just picked that move out as an example, but I believe it's actually bad for Black:
The reason I know this is that I had that exact opportunity as White in one of my games recently, but I missed it and only found it when I analyzed the game afterwards. I won't miss it again though! :-D
