New Build

My wife and I are building a home and as I am a gamer and my wife works from home, having fast and reliable internet is huge for us. We are both wanting to be wired into the internet. I am not the most tech savvy when it comes to home networking. I am trying to think what I need in the office for outlet wise to have the modem and router in there so we can connect via cable easily. I was thinking of asking for a coax cable into the room to connect the modem to it.

What are your thoughts on one coax cable for that room? Should I be asking for different outlets in the room or in other places? What other things should I be considering in my house?

Any or all help will be appreciated! Thanks!
