I think there are special cases here like popcorn, but for the vast majority of food, home cooked likely means less exposure to plastics (packaging), additives, excessive oil, less healthy oils, etc. Restaurant food tends to evolve to taste especially good or last a couple of days longer than usual or compete with other restaurant food etc., all of which is not desirable at home (or even worth optimizing for).
