Hi scribble,
Replace the word "hold" with thought of "put it in a 150°F place or oven on lowest setting to keep warm and safe until you are ready to slice it/serve it"
Maybe Baked Chicken with Chimichurri/Gremolata and oven roasted root veg.
I like the Baked Pasta casserole concept. Anything from sausage, peppers, onions with red sauce, Chicken, veg and mushroom sauce, Chicken/pork/beef mexican lasagna using corn tortillas, Any layered casserole where you like the flavors and ingredients.
I like the roast concept also. Roast beef dinner! Roast Pork dinner!
Do something with a pork butt. Asian flavors over veg fried rice, build your own Carnitas taco/burrito, BBQ'd pulled/chopped pork sand.
Maybe just rework your boeuf bourgignon and substitute beer, for the red wine, Voila! Carbonade Flamande
To stay with a casserole, do a search for "(fill in Nationality)" casserole. I did "greek" and got Moussaka and Pastitsio, both good casseroles! German Casserole showed A Cabbage, potato, sour cream and sausage dish, another had Sauerkraut, apple, potato and pork.
Ham works in a lot of these also.
Good luck and let us know what you decide on!
