A good way to play and reach chessmood openings would be 2.Nf3 g6. If W plays 3.c4 you can reply 3...c5, if 3.g3 c5, 4.c3 b6 and if 3.Bf4 Bg7, 4.e3 d6.
I used to play 2.Sf3 c5, which I also liked and I think GM Avetik likes that also as an alternative, if your rating is not too high (below 1800 or so)
After 1.d4 Nf6 2.Nf3 I like 2..c5. It also fits in the Benko-repertoire.
Here some illustrative variations:
(a) 3.d5. After this move you can play (1) 3..b5, or (2) 3..e6 with the idea 4.c4 b5 (Blumenfeld Gambit; note this can also arise after 1.d4 Nf6 2.c4 c5 3.d5 b5 4.Nf3 e6!?)
(b) 3.c4 (this can also arise after 1.d4 Nf6 2.c4 c5 3.Nf3) 3..cxd4 4.Nxd4 e5 5.Nb5 d5 6.cxd5 Bc5, a very interesting gambit
I know of this 3.d5 e6 4.Nc3, and I understand that after 4..exd5 5.Nxd5 Nxd5 6.Qxd5 you may not like the hole on d5, but it does not seem to be too bad after for instance 6..Nc6 7.e4 Be7 8.Bc4 0-0 9.0-0 d6 10.Rd1 Be6 11.Qd3 Bxc4 12.Qxc4 Qb6. I know, this is not a forcing line, but just an example line.
Show me what line you are exactly afraid of, and I'll try to convince you otherwise. ;)
Side note: 4..b5!?/?! is also interesting (but maybe dubious). White can go wrong here in many ways. The best for White seems to be 5.dxe6 fxe6 6.Nxb5 d5. But it is Benko-like.
