I would buy fried chicken, but it sounds like you want to make it from scratch.
If you want to try to eliminate the need for flatware I guess sandwiches are easiest as other people have suggested. If you make up the sandwiches ahead of time I suggest you don’t put the condiments on them if possible. I’d bring two types of chips, maybe plain potato chips and some other something. The bagged popcorn might go over well. Fresh veggies like carrots, green beens, mini peppers, and some sort of dip if you think it is necessary. I’d also bring a bunch of Clementines, people can easily peel them and no need for a fork. Other fruits like grapes and strawberries that people can eat easily.
Shrimp with cocktail sauce is also a possibility and would be a real treat. If we move into needing a fork you could do a Meditteranean theme with the shrimp and also do a cold orzo salad, pita chips with humus, and marinated veggies like an antipasti adding also olives and salami, and whatever other meats you prefer. Bread roals or bread sticks. A cheese plate might also go nicely with this and some wine.
Lastly, I would bring either chocolate cake, chocolate candies, or some sort of assorted cookies,
