I would keep it simple, and do it well. Butter and broth if you’re shooting up, but I also don’t inject if I’m hitting the brine. I get as much chopped and prepped and in the fridge as I can the day before, often in the vessel that it will cook in (turkey, yams, dressing, corn casserole). I use aluminum disposable pans where possible when it won’t affect the dish so there’s less clean up. If you’re coming over, you’re bringing dessert and/or wine. I do crudités and a cheese plate instead of salad because you can pick and wander around before dinner and then save the table for the real food.
