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.

What goes in these structured wiring cabinets?
