I’m considering a Nikon D7000 body and may upgrade to an FX Nikon body later. How can I identify whether a lens is DX or FX when browsing listings like B&H? I’d also like to know the naming used by third-party brands such as Sigma and Tamron. Can FX lenses be used on the D7000?

For Nikon, it will list with "DX" in the name, otherwise its a FX lens. For example, on the B&H page, it lists the 35mm DX as "AF-S Nikkor 35mm f/1.8G DX Lens".
For Sigma lenses that work with Nikon, its the "DC" that indicates a DX sized lenses.
For Tamron lenses that work with Nikon, its the "Di II" that indcates a DX sized lenses.
If it doesn't have one of those, its a normal, "FX" sized lenses.
(And realize that FX lenses will work with the D7000, as well as the DX lenses) .

For Nikon lenses, crop-sensor lenses are usually clearly marked "DX" in the lens name. If a Nikon lens does not say DX, it is generally an FX/full-frame lens. Example: "AF-S Nikkor 35mm f/1.8G DX" is a DX lens.
For third-party Nikon-mount lenses:
- Sigma: "DC" indicates a DX/APS-C lens
- Tamron: "Di II" indicates a DX/APS-C lens
If those crop-format markings are not present, the lens is generally intended for full-frame/FX coverage.
Yes, FX lenses work fine on the Nikon D7000. In fact, buying FX lenses now can make sense if you expect to move to an FX body later. Just keep in mind that DX and FX options are not always direct equivalents, and FX lenses are often larger, faster, and more expensive.
