Gigabit Routers

For your situation, WAN to LAN throughput will be most important in order to take advantage of the bandwidth. That dictates the speed from WAN (where your modem interfaces with the router) to the actual router part of your router (interfacing with everything else on your network). A lot of the mediocre or budget consumer routers can only handle a few hundred mbps WAN to LAN. A non-issue for the majority of us who aren't lucky enough for gigabit fiber, but an unnecessary limitation for you.

FYI, you still won't get your full 1 Gbps on any consumer router, but some do handle upwards of 900-930 mbps, which is good enough. Here's a ranking by WAN to LAN throughput: LINK

You'll notice the flagships rank near the top, like the Nighthawk, but there are a few budget-oriented routers in the mix, too.

But, as SG Geaux said, most of the devices you named (wireless) have their own inherent limitations, so don't expect remarkable improvements in download speeds necessarily. Think of this LUS fiber upgrade as getting a larger pipe rather than a faster pipe. What a decent router will give you is the ability for all of those devices to operate simultaneously at full saturation (or enough to not notice any hiccups) because of the extra bandwidth you'll be getting. I'd recommend the strongest consumer router you can afford.
