I might be concerned about teflon and similar non-stick coatings, but not really about ceramics. Humanity has been using ceramics for ages, and we haven't found any adverse affects yet.

Porous ceramics can easily breed bacteria, good and bad. And glazes on ceramics can contain all kinds of delightful compounds that can leach out. You certainly don’t want to eat or breathe unfired glaze.
As for ceramic nonstick cookware, I’m not convinced that such a thing exists. I think that “ceramic” coatings are actually sol-gel, and I can’t find a straight answer as to what is in them. They do advertise that they are fluoropolymer-free, and they seem to be stable to rather higher temperatures than PTFE.

Yeah, the downside is whatever that stuff is, it obviously doesn't bond as hard as PTFE, because every ceramic nonstick pan I've seen degrades even faster.

Ceramic glazes have been problematic [0].

Just make sure it's PFAS free and not just PF(X) free for some X; 3M is hell bent on getting this shit into your system
e.g. some of the 'copper coated' stuff that is 'PFOA' free
