You're gonna love the SW's one! Hands down our fave! The only "extra" we've done that we'd repeat every trip if we could! Very hard to top the value in food (great desserts & their savory options are wonderful) adult drinks, & perfect view of the show! (Get to the party early to be the 1st in, then head out before the Storm Troopers to get a spot along the front rope. You'll still get to see them march out, plus the best spot in the designated area).
We were underwhelmed with the Wishes one. Tons of sweets (which in my opinion were just "ok). But, the view was worse than any other we normally have. We won't do it again. We're happier grabbing our own ice cream & getting a spot in the old FP area.
For a (maybe one & done) different experience, Pirate & Pals was a lot of fun. Not really a dessert party as the food selections were not abundant. But, the character M&G's were awesome, the boat guides hilarious, & it's a unique experience watching Wishes from the water. We're glad we experienced it once. While we saw families with kids, there were also a lot of adults doing it on their own. Def not just a "kid" experience. We even saw a proposal with Peter Pan.
We've never done the Illuminations one for the same reasons as above. But, many friends say it's their favorite due to the wine and view of the show.
