Proper order of multi-course meal, not sure how to order these for our wedding

We are having a four course dinner with a sherbet intermezzo but the caterer asked if I had a preference on the order of the appetizer and second course. I assumed the palette cleanser would be done directly after the crab cakes so I think we should do the burrata first? Appetizer- Prosciutto and burrata salad First course- crab cake a la plancha Intermezzo- citrus sherbet Main entree- Filet Mignon, roasted chicken, or nut free pesto gnocchi Dessert- wedding cake and gelato cart submitted by /u/InevitableCareer5
