It kind of depends on how much you cook and how many you're cooking for. I would want: 4 saucepans of varying size, 3 cast iron skillets of varying size, one dutch oven, one large stock pot, one large stainless steel skillet, 2 pyrex 9x13, 2 pyrex 8x8, several corningware casserole dishes with lids (or similar brand), 3 baking sheets, slow cooker, hand mixer, 2-3 colanders, 3 cutting boards, 2 loaf pans, 2-3 cooling racks, several mixing bowls of different sizes. I'd also want to keep my food processor, instant pot, and ninja blender, but those things definitely don't get as much use as the other items.
I have a deep nonstick skillet that I almost never use - I could definitely part with that, and a few extra baking sheets I don't like and rarely use. Also I could get rid of my broiler pan. I used it a lot more when I ate meat, but haven't used it in years now.
