You can call sched_setaffinity(), which is enough in this case.
For other use cases, I'm not sure exactly what you had in mind. You can acquire a "file handle" (as you mentioned upthread) via pidfd_open, but I don't think there's a whole lot you can do with a pidfd that you can't do with the PID. But that's not really a problem with CLONE_STOPPED; it's a problem with the entire kernel API for not exposing more features for this sort of manipulation.
