Welcome from another Tidewater member! Lots of great info here.
+1 on the conduit between floors for future expansion. So much easier and cheaper to install cables now, but if you are running out of time to pull cables before the insulation/drywall crews show up, conduit runs can help reduce frustration and drywall patching in the future. Also consider a conduit stub-out for possible external security/surveillance devices (like to the end of the driveway) or to the shop if it is detached.
Good luck with Cox. Hopefully you can run the service and have the demarc close to your network closet or main electronics area. My demarc is on the side of the attached garage and the cables run up the wall to the attic, over to the other side of the house, then down into a first floor closet with a horizontal stretch between floors for good measure.
Additional suggestion is to take pics of your buried utilities with measurements from good reference points that won't move, like the house or corners of the shop. 811 is good but a measured survey of the property is so much better.
