House remodel, adding ATT fiber - what runs to set-top boxes

ATT service would be Ethernet (cat5e or better) or wireless, if desire to have cable service would need coax (RG6). Recommendation is run at least one of each to provide flexibility and best to run (2) Ethernet to each location.

 Note that cable tv service is over 60+ years old while home internet, pre web BBS like Compuserv) was from the 1980s, the web was 1991 making it 32 years old.The first wireless network (WI-FI) started 1971 but did not become consumer Wi-Fi friendly till 1997 or 26 years ago.

Satellites (commercial) have been since 1962 but consumer satellite internet has been since around 1996 or 27 years. 

This means most residential entertainment in use today occurred during GEN Y or Millennials birth years. 

A new customer will not be able to order U-verse IPTV, so it's really a moot point.  To answer your question, though, the preference would be Cat5e or better Twisted Pair cabling from each TV location to the location of the Gateway, or at least an Ethernet switch connected to the Gateway.  Excluding the single DVR Receiver (which must be Ethernet-connected), up to 4 Receivers may be fed wirelessly over 5 GHz Wi-Fi from a dedicated WAP.

I would recommend getting a low power Electricity installer to recommend a structured wiring system for the home, running one or two legs of Cat6 from a central wiring point to each room that might host a TV.  Even though you can't install U-verse, most streaming devices (including those provided by streaming platforms such as DIRECTV STREAM) and smart TVs will support a physical Ethernet connection to the Internet, which is generally more reliable than Wi-Fi.  It would also come in handy to have a Wired connection to XBOX, PS5 or similar devices.
