New Home Construction with DirecTV and AT&T Fiber Internet

I’m having a new home built and want to get AT&T fiber to the house as well as have my DirecTV reinstalled (existing customer for both and I believe the AT&T fiber junction is at the corner of my new property).  I am installing Cat6 in the house for my hardwired network and plan to install a structured media panel centrally located in my walkout basement on the stairway wall leading from the first floor down to the basement.  This stairway wall (and media panel location) is probably around 30 feet from the outside wall where the AT&T fiber will likely enter the house.  I’m not a sure about where the DirecTV will enter the house but it’s probably a distance of 45 feet or so once it goes down the side of the house and to the media panel.

I’d like to be able to have the DirecTV folks do the install before the house is fully complete (before siding is on) so I don’t have holes drilled in siding and stuff like that.  Also with both the DirecTV and AT&T fiber internet, I want to run everything to the media panel before signals go out to the rooms.  Right now I have a lot of flexibility because nothing is finished so I can move things that may not suit where the installer may need it to be.  How do I make sure things are where they need to be and routed properly?  What recommendations can anyone provide so I can do this properly before the house is fully completed instead of after the house is done and I have to drill holes in siding, drywall, etc.?

*also posted with AT&T to get feedback on that install.
