This is a highly complex question in spite of its apparent simplicity. Breakfast is a variable for me. Most often it is coffee and toast. I make the coffee. My wife makes the toast. On weekends we upgrade to a cinnamon roll. From time to time I will grab an egg or two. This is me at 75.
When I was younger weekends and days of physical labor were started with a full breakfast of coffee eggs, biscuits gravy, hash browns, and sausage.
Very rarely I will make pancakes. Oddly oatmeal, or any breakfast cereal, is an evening snack.
