We had a full house one year, with 7 house guests for a week, aged 12 to 70 at the time, plus me and my 2 DCs.
These are the meals I remember having at home in our dining room 
Take-out pizza one night, after a movie night. The older people had been at an open house and had filled up on appetizers, homemade Chex mix, and cookies
…
Roasted lemon oregano chicken quarters , 12 yo had requested chicken. Then she wouldn’t eat the chicken when it was served . Turns out she only ate boneless skinless chicken breast, something that is almost never cooked at our house. LOL…
…
Caesar salad
meat and rice stuffed grape leaves served warm
cheesecake
…
New Years Day
cold cherry soup
Beef tenderloin
scalloped potatoes.
cauliflower cheese
…
individual lava cakes, one relative brought a kit. This was a pain in our tiny kitchen, to use ramekins to make lava cakes for 10 people , and I would not recommend individual lava cakes for a group larger than 6, or for someone who has been cooking all week. I would make a larger self saucing pudding cake or Pouding Chômeur instead.
…
if I had an open concept house, I would make things like Make Your Own breakfast burritos, taco bowls, Make your own Cobb salad.
I also do Breakfast Casseroles or Stratas when we have company.
I usually make a Huevos Rancheros casserole for Xmas morning
Sticky Buns and Butterhorns are also popular with our family at group gatherings.
