Another option:
Between modem and router (Orbi satellite), I have a 5 Ghz WiFi backhaul. Seems to me, I get the same protection as fiber against lightning (along with absolute protection from mice). Galvanic isolation, too, and less cable clutter. Haven't noticed issues with drop-outs. No new converters and PSUs at either end as needed with fiber. Complete flexibility if I want to move the router. No drilling, no stapling. As I recall, at least one HiFi company (Auralic?) recommends WiFi over ethernet for best sound quality (though I'm skeptical it makes much difference if we're comparing equally strong signals).
