re: The importance of 200g of protein/day.

I don't ever supplement to hit 200g. The key is not just eating the typical pastry style breakfast and instead get 40g of protein in the morning. I scramble up some ground turkey, eggs, and spinach over the weekend and wrap it in a burrito and eat that for the week. You can throw in some Greek yogurt and you're at 50g already. For the week I usually make a huge chuck roast in the crockpot (~70g per serving) served over rice, some chicken pasta (50g per serving), and some shrimp and rice (45g per serving). That's over 200g in around 3000 calories. But if you're trying to keep calories lower just air fry some chicken thighs/breasts. I'll also sometimes do a homemade chicken noodle soup heavy on the chicken so it's more like a stew (600 cals with 70g of protein), pork roast (350 cal, 35g of protein), hamburger steaks (640 cal, 64g of protein), or spaghetti.

Point is that there's plenty of high protein options to keep things fresh that are easy to make at home and prep for a week at a time.
