My house got "hit" a couple years back. I have no idea what the actual path to ground was, I suspect it was mostly induced surges actually, as I lost many of my networked devices, a couple HVAC boards, a garage door opener board, and a an alarm panel board. Probably also an HDMI port or two and the cable box. I was fortunate that my [cheap] ethernet switches acted as fuses for the computers.
Like David, I installed surge protectors on all my main and sub panels (and on my HVACs - - the DC motor controllers for variable speed fans are expensive). Knock on wood, no issues since.
I'm not sure what else to do for the low voltage stuff - - it was already on surge protectors and UPS. Fortunately, so long as its limited to routers/switches, it's not terribly expensive to replace.
It's pretty amazing how quickly a close bolt of lightning can wreak havoc on our modern electronics.
