When you create a new Wordpress site, the first user created is user #1 and given the Administrator role. Is there anything special about user #1 that would make it unwise to delete it? (Assuming that there were other users with Administrator role.)

Yes, that’s safe. I have done that. The core does not rely on the existence of such a user.
There might be some broken plugins whose authors think user 1 is always there and an admin, they will not work properly. On the other hand, this is a very simple test for a plugin: If it doesn’t work after you have deleted user 1, it is probably very insecure, and you need an alternative anyway.
