This is what I was going to say as well. NFTs are young still. Who knows where they will go. Assuming governments finally start accepting Crypto then NFTs will be a great use case for records. You could have your passport, health card and information stored as NFTs on the blockchain.
From a current platform side of things, it is really fun to watch how some companies are doing with NFTs. The biggest use case currently is NFT related gaming. I love seeing projects like NFT Draft coming out (later this week) that are using NFTs on WAXP to push through normal NFL "Drafts" and make it a fun game. Winning massive money prizes are nice as well.
