Wedding Buffet ideas

There are so many good looking recipes on here! I am looking for advice on narrowing down some ideas for a wedding reception dinner for 40-50 people. It is an outside summer wedding, not too formal, and I want the reception to be a buffet for easier service.

I want the food to be sort of like an upscale picnic.

I am looking for recipes that can be prepared largely ahead of time, so that the whole family isn't inside cooking a few minutes before the wedding.

The ceremony is at 3:30 and then I want to have a few appetizers to tide people over while the bridal party is getting pictures taken. I am thinking about the gazpacho, maybe in individual cups, the caprese skewers, a fruit tray and cheese tray, maybe some crackers and dips? Then for the dinner I am thinking a couple different types of salads and then??? I'm really stuck on what meat options to serve that can be prepared in advance.

Any advice? Thanks!
