In my view, NFTs are just digital certificates of ownership. In theory, NFTs can be used to transfer ownership of anything that is non-fungible or unique in some way. A piece of land could be sold with an NFT. However, in the real world, the ownership of any property is verified by The State. It is the only entity that can enforce a dispute around any physical asset, and that will not change anytime soon.
Tickets to attend musical, theatrical, or sporting events are good candidates for real-world use cases of NFTs. Counterfeit tickets could be eliminated.
