I only have WiFi but want to have WiFi + Ethernet/MoCA in my house

I'm a first-time home owner + new to TELUS so I don't have much experience yet with home networking.

My Fiber is entering in through the basement ( Imgur: The magic of the Internet- first image). An ethernet cable runs from the ONT to an ECB6200 MoCA adapter. From the MoCA adapter a coax cable runs to the living room where I have set up my Telus Wi-Fi Hub.

However, I have coax outlets in each of my rooms (5 in total), which I would like to use to set up a wired internet connection throughout the house. None of these work right now (other than the one in the living room) , but in the basement there's a whole bunch of coax cables (Imgur: The magic of the Internet - second image), which don't seem to be connected to anything. e.g. they come out of the ceiling and go back up into the ceiling - it almost seems as if the previous owner connected the coax outlets in the house to one another.

Based on this, how should I approach this? Should I simply get a coax splitter, put it after the ECB6200 MoCA adapter, connect all coax cables in the house to it, and put another MoCA adapter in each of the rooms? I don't believe my house was wired for ethernet as I exclusively have RJ11 outlets.
