Non stick: alright for eggs and other relatively low temperature stuff. Make sure you only use rubber, plastic, or other soft utensils, and never clean it with a scraper or steel wool. The surface of the non stick is fine as far as I know, but if you go deeper by getting too hot or scraping with something too hard, you can expose the toxic chemicals.

Stainless: my go to. Use whatever utensils you want, and clean it however you want. The main thing to make it non stick is heat the pan up hot enough that when you splash a bit of water on it, it beads up and scatters. Then use plenty of oil. The main downside is you usually can’t put them in the oven.

Cast iron: better in use than stainless, but harder to clean. Upside is you can use whatever with them, and you can swap between oven and stove. Downside is you can’t clean them the same way as anything else.

Agreed. “Chunky water” type vegetable soup is very different from “thick and gloopy” pumpkin soup
