Buy your own router. Depending on your home layout, I woud go with a good mesh system or a router that allows you to add mesh satellite units so that you can get great WiFi throughout the house.

My personal favorite for future proofing is the TP-Link Deco AXE5300 with 2 satellite units. A bit pricey, but not that much more than the G3100 from Verizon.

If you do a mix and match change to your service, Verizon might add the G3100 for free. Look at what they have on their web site.
