Aside from immunity to radio signal jamming, there's no worrying about batteries/charging or ugly wall warts. You can also power your PoE switch from a UPS to survive power outages.
It's also vendor agnostic and fairly future proof. What I mean is while you might have lock-in with cameras/NVR today, you aren't locked in forever; worst case is you may be forced to replace everything but the wiring, but that's by far the hardest part to do in a finished house. The Cat5/6/7 will be useful for the foreseeable future.
