Your choices are severely limited. So, the choice is between the minors. With three-three minors, it is widely considered automatic to rebid two clubs, even with a serious strength disparity between the suits, in order to preserve bidding room. Here you are strong enough to make the natural, invitational bid of two notrump, following the modern style under which this shows a hand too strong for a one-notrump opening. You are far too weak for two spades, which shows full reversing values, and the hearts are too short for two hearts.
All choices are inadequate, indeed dangerous, here.
This hand type represents one of the glaring flaws in the current method of handling the forcing one-notrump response. However, that's only a fraction of a flaw, especially when compared to the near-nauseating prospect of rebidding two clubs. There is probably no future in bidding two spades. You are not interested in spades when partner lacks four, nor in encouraging a heart preference. And you have nothing other than notrump in reserve for the next round anyway.
