Wishes/HalloWishes/MK Fireworks can be viewed from any of the monorail resorts, WL, FW, the TTC, and (if you're lucky) the water transportation.
Contemporary - no view from Chef Mickey or the Wave. You can watch the fireworks from the CR 4th Floor Observation Deck or California Grill (if you are dining there).
California Grill - the restaurant has an observation deck where you can watch Wishes. They pipe in the music. A few tables have a view of Wishes, but those are pretty hard to come by. You can ask for a window table, but they do not promise to have one available before fireworks. If you want to eat here, I would aim for an ADR about 2 to 2.5 hours before Wishes. Personally, I like the observation deck because you don't have to deal with reflections in the glass.
Polynesian - no view from Kona.
'Ohana - a few tables have a view (maybe a dozen or so), but most do not. I would not go with the plan to see fireworks from your table. There are some reports indicating that folks do get up and move around to see the fireworks. This would be the approximate view (you can see the castle to the left of the main wall support).
Grand Floridian - no view from Citricos (a few bursts might be visible, but not really anything worth seeing) or 1900 Park Fare.
Narcoossee's - this is my favorite restaurant in WDW. Most window tables have a view of Wishes, but the view is often blocked by folks standing out on the veranda. You'll probably have to go outside to watch as well. Then dim the lights and pipe in the music (inside the restaurant and outside on the veranda). You can request a window table. I would aim for an ADR about 90 minutes before Wishes.
I've not as familiar with the layout of watching Wishes from WL or the TTC, however, I you cannot see Wishes from inside WL, so there is no view from Artist Point or WCC.
