Catering is one of the pricier things in a wedding. Usually it's assumed to go with the standard one or two meats and some sides, plus an extra course before or after. But if your wedding isn't around dinner time, you may want to consider other ideas.

Is your wedding in the morning and the reception right after? Follow up with a salad bar/buffet. Not overly expensive, there can easily be sufficient variety for everyone to be satisfied. And there's not much reason to worry for people who may spill something on a rented suit.

Early afternoon? Perhaps hors d'ouevres maybe with party trays containing buffalo wings, shrimp, etc.,.
This would also work well with a bar tender and be fun for most people.

If your wedding reception isn't during a normal mealtime, between lunch time and dinner or so, then cake and punch may be the way to go. This is simple and effective.

For the evening you have the standard one or two meat choice, with a few different side items and drinks. This can be in conjunction with other courses such as an appetizer and dessert.
