Speaking as a complete noob here, what are some alternatives to PFAS linings? Wax? Plant-based plastics?

Yes to both of those.

I actually doubt that plant-based plastics are any better in additives than oil based ones. Wasn't there some years ago whole thing about those reusable "bamboo" polymer coffee cups. That actually they do contained not so beneficial chemicals.
