Resort preferences are such a personal attribute it's tough to recommend.
Are you going to stay in a 1-B/R Unit. If so, then I'd recommend OKW as your first resort simply for the WOW factor of the spacious 1-B/R villa itself.
If you're in a Studio, then something other than OKW since the others have the sofa which is more relaxing and less like a regular hotel room.
For theming I think VWL is the best, and it has 'fun' transportation via boats to the MK.
For dining, you might try SSR due to it's short walk to DD, or BWV/BCV which have a number of restaurants around the lake and in the various resorts located there.
If you like Epcot and MGM Studios a lot, again BWV/BCV are nice and you can walk if you want.
Whatever you choose, I'm sure you'll have a great time.
