When you click through to sign-ups, it will ask you to add 3-10 requests (things you're happy to receive) and 3-10 offers (things you're happy to create). And then, as you say, two people who sign up for something similar can be matched with each other.
But you can only offer or request things that have already been nominated. The tagset is basically a list of what's been nominated: https://archiveofourown.org/tag_sets/5325
There's an optional 'Description' box where you can write a little bit about the kind of things you like, things you don't want, and suggested prompts if you want to give them. That way your assigned creator gets some guidance beyond just characters or relationships.
You can't see what other people are offering, but if you look at the 'Requests' page you can see what other people are asking for: https://archiveofourown.org/collections/BlackIsBeautiful2021/requests.
