To answer the subsequent question, I don't think after 3♣ I can bid more. I would be extremely uncomfortable selling out, but I think I'd have to. My second choice of bid, if I feel I'm worth pushing to the 4-level, is 3♥. It's a mild overbid (someone mentioned the lack of A/K as a detracting factor - I agree) but at least if it is a double fit deal (as it turned out to be) then partner can know whether to defend or compete and I'll feel my hand is shown then and I can leave partner to make the call. I dislike 4♣ because that is a blind call and doesn't help our partnership tell if it's a double fit deal or a misfit deal. But it, at least, doesn't promise the extras that I don't think this hand has. So a conservative 3♣ just ahead of an aggressive but descriptive 3♥ call in turn ahead of a right-on-values but otherwise undescriptive 4♣ call.
