Great review, it's a lot easier to break in by bouncing or knocking the safe (if not mounted) and will force the solenoid piece to go down for a split second and someone can turn the lock. I've carved out a grove on the solenoid cylinder so it's harder to just slip it through, it'll catch the lock mechanism first. Maybe have two solenoids, one on horizontal orientation and it serves as a lock for the solenoid plate so it does not get pushed down via drilling a hole or via the holes from the lights.
