Nothing in my home has SFP ports other than my routers and my primary network switch (two, hooked up to the routers). All of my computers and USB adapters for laptops expect RJ45 at 10/100/1000/2500/5000/10000 Mbps. None of my runs are over 50 ft. So IDGAF about how much "better" fiber is. It's unfathomably worse when you factor in the cost and work I'd need to do to convert everything and every new adapter I'd have to buy or build (can I get an $80 USB SFP adapter? Do I have a cable?). The extra marginal cost in electricity will take longer than the lifetime of my equipment to exceed the cost of redoing everything.
