I think the most likely thing you'll see popping up is NFTs as tickets to sports games. That's one of the few NFT use-cases I really love and think makes sense.
The thing I love is the idea of atomic transactions. What does that mean? Well the transfer of a ticket for money could be a single transaction. No ticket without money, no money without ticket. Sure, you could use some tech to do this - maybe rely on Paypals guarantees to get your money or ticket back if the other person is fraudulent. But how do you guarantee the ticket is authentic? Well I can include a verification step in the transaction to only send my money if the ticket is valid with a smart contract. Now you have a peer-to-peer trustless safe method of trading tickets with strangers. The ticket providers can mint x tokens for a release and enable a safe resale market while users can feel safe buying and selling tickets online.
An NFT can store on-chain metadata. A simple boolean flag would let you mark it as resellable or not. In minting the tickets you can create a validator that checks authenticity but you can check these things yourself: that it originates from the organization for example. The metadata is immutable so if it's come from the organization it's authentic. Because NFTs are tokens are money you can transfer USDC for BackstreetBoysGig#Ticket1021 where O2ArenaTicketVerifier authenticates the ticket as part of the transaction only confirming it if the ticket is resellable and authentic.
How does a company know their tickets have been resold, if they don't want that to happen? Well you look at the tx history of the NFT - if it's been traded > 1 time it's been resold.
Compare these potential benefits with the existing ticket industry (including resale sites) and you see several benefits. You can remove intermediary companies meaning people pay less in fees and you can avoid ticket fraud. Is this an issue? Yes: https://www.theguardian.com/money/2020/feb/24/touts-who-made...
Trust-less transfer, verification, & sales. The ability to provide additional value after the event. The ability to provide perks to recurring attendees. Means and reason to sell the ticket after the event.

This... This can already be done and is already being done now, without any blockchains. There's literally nothing difficult in doing this.
