Pino Gris/Grigo for a white that is fairly middle in the dry/sweet category, I have yet to find a bad bottle. Washington State makes some great whites, as Does Oregon (Willamette Valley).
Be careful with Pino Noir, I've had VERY good and also VERY, VERY BAAAAD. One I could barely drink ended up in a red sauce, which was all it was good for.
If you are looking for a sweet wine, try a german reisling.
If you are looking for a REALLY sweet dessert wine, try German eiswein (pricey, but worth it), but only about a 3 oz pour after dinner. More is too much.
