How is the queue ID determined? Completely randomly, or does Postfix try to avoid re-using an queue ID too quickly?

The queue ID determination is not random; if you are feeling curious, peek inside src/global/mail_queue.c. As mentioned in the comments therein, the only guarantee is that no two queue entries will simultaneously have the same queue ID.
