USB sticks are generally cheaper for the same capacity, and some people think
they're more reliable (I don't have a personal opinion).
Raspberry Pi 3 B can indeed boot from USB, and the Pi 3 B+ can also do PoE,
and network boot (although I doubt either is a help for this project).

a) not necessarily - there's no reason server keys need to be unique,
especially in a private network space
b) the simplest solution if you want unique keys would simply be to delete the
keys from /etc/ssh in the image before replicating it - then they will get
automatically created when each card is started for the first time
