To solve this issue, your suggestion of 2NT, Nat GF is a good one if you have it available (my system doesn't). Over it responder should not bid 3NT with all 2=5=2=4 shapes. If 2NT promises two hearts (it should), then 3H should show doubt about NT and a good suit. 3C should be doubt as well, not 5/5 because opener could have asked, and you would have opened rather than passing anyway.
If 2N promises two hearts then it makes sense for 3H to show a good 5-card suit as responder can just bid 4H with a 6-card suit. (And if responder is an UPH -- and so might still have slam interest -- he can bid 3H then 4H or show a control/SPL with a strong 64.) It probably is reasonable to require a doubleton heart for 2N: the auction is GF so O must be interested in a choice of games. Of course that means some other hands that want to offer a choice of games have to relay (unless playing the methods discussed below), say a hand like KJxxx x Axx AKQx where you might want to play 4S if partner has Ax or Qx.

A good alternative method is to play some of the available relay-breaks by captain as asking about the quality of the doubleton(s). I haven't played this method, so don't know the exact scheme, but this seems a pretty good fix.
There are a number of possibilities. My preferred method is to play
3D asks for stopper(s) in doubletons (denial method, following usual rules for ordering suits)
3H asks for AKQP
3S shows a SPL in the major teller has shown (the shorter suit if teller has shown H+S or C+D), initially choice of games but could be a slam try, so teller should bid above 4C with extras (can be showing AKQP, RKC responses or NAT -- i.e. control-showing -- as you wish).
4C asks for controls (A=2, K=1)
Of course, you have to decide whether Qx qualifies as a stopper: in Ultimate Club only Kx and Ax counted.
But that adds some complexity -- too much for some. In which case, given Shevek's methods, it seems reasonable to define 3S as asking for a choice of games. It could be asking about the higher (or lower) of the doubletons or the long suit, or just a general direction shot. The exact choice should depend on what 2N (instead of 2S over 2H) means -- no point duplicating options. In which case, maybe it makes sense to reserve 3S for hands like KJxxx x Axx AKQx where O is looking for a choice between teller's doubleton M and 3N.
