Take your pick! Here's some of my favorites!
60mm micro f/2.8
All of the above, I think, actually benefit from the 1.5x crop factor.
The rub comes on the wide end. If you own a DX body now, I think it's better to buy a DX ultra-wide, like the excellent Tokina 11-16mm f/2.8 (it's the only non-Nikon lens I own), so at least you can have some ultra-wide fun right now with your DX body (or, put that money toward buying the FX body sooner). Then, just wait on your FX wides (like the awesome Nikkor 14mm zoom or prime), until you get the FX body, since you won't get much "bang" for the buck with "wide" FX lenses on a DX body. For example, the 14mm isn't a great choice for DX (it doesn't "translate well")--it's not that wide in DX, and it's huge (and heavy!). A DX ultra-wide will be smaller, lighter, and wider (and, less expensive!).
Once you do get an FX body, then you can go wild with short lenses. Here are some of my favorite short lenses for FX:
