Two in-wall structured wiring cabinets in our new garage.

I need to install gear in these two structured wiring cabinets in the garage of the new house we are finishing. I don’t know exactly what to put in them and seek advice.

The installed cables are:

Blue CAT-6a Ethernet cables go to outlets (RJ-45 jacks) in four rooms. Internet will come from the city’s new fiber optic system.
Coaxial cables go to four possible TV locations. They will carry signals from the over-the-air TV antenna that will go on a pole outside. We will not have cable TV or Internet service.

Soon to be installed are:

A coaxial cable from the TV antenna.
A fiber cable from the street.

Both will come underground and up into the garage through a conduit between the back of the house and the hole (not visible) in the left side of the left cabinet.

So here is what I think I need:

A patch panel for the coaxial cables, so I can either distribute the TV signal or patch it through to one TV at a time.
An ONT (optical network terminal) to serve as the router between the fiber from outside and the four ethernet connections inside.

Here is what I don’t know:

What the fiber provider (GigabitNow Bloomington) will provide. I know they will need to terminate fiber from the street with an ONT that will go in one of the cabinets, but I don’t know whether they will provide, or I will need to get, a way to distribute service to the four Ethernet lines. I see ONTs sold online that have four Ethernet ports, but I don’t know if the provider will welcome my getting one or not.
Whether I will need an in-line TV signal amplifier. My antenna, which I’ve already built and tested, has an amplifier already. The question is whether I will need more amplification, especially if I am distributing to more than one room, and not just patching through one room at a time.
Exactly what the best practices are for attaching devices to the inside of these cabinets.

So that’s it for now. Thanks for any input you’ve got.
