I think celebrity style portraits get close because each person might require a very different look.
I can’t think of any examples where it doesn’t result in a short series of photos though. For a poster or something one might be used but variants usually show up in other circumstances.
Corporate headshots need to look similar across people.
I don’t know enough about Ansel Adams and how his work was/is presented but it does bring up postcards and stock photography as possible “singles” genres. For very good reasons they aren’t usually considered great photography.
Note that many photographers are known to spend time processing and printing. W. Eugene Smith for instance was notorious. His work was still highly serial.
