The speed limit for MoCA out of the ONTs is 100Mbps, which Verizon no longer sells as a speed tier. Coax therefore would only be used for TV service, as Ethernet is the only option to get connectivity from it.
What you can do is use MoCA 2.5 adapters between your ONT's location, and the location of your router. Just be sure that this MoCA WAN link between the ONT and the primary router is a "point to point" connection, as in no other devices connect up to that MoCA network. Some adapters allow you to specify MoCA Channels and MoCA Network passwords to separate things. Other times, it's good to physically separate the ONT WAN link from your MoCA LAN by not using the same splitter and Coax for both LAN and WAN.
Or, if your network allows, relocate the main router near the ONT, then use MoCA to distribute your network to any Wi-Fi access points and MoCA wired devices.
