Feeling lost with choosing a cooking pan. Everything has some sort of toxin, stainless steels have nickel and cadmium, even hexclad or cast iron have something. Really what should I buy?

If anyone's gone down the rabbit hole and can explain it to me, if I didnt have 2 kids and a newborn, I would have researched my ass off, but I really really cant :( I just know that non stick is bad :(
