3 words. Wire Is Cheap.
And 3 more words. Conduit is Cheap.
Based on the limited knowledge I have of your situation, whatever you do, put in as much wiring as you can afford, and then add 3 more. The more you furture proof the better.
If you are pulling the wire yourself, shop around. And 1 wire I found that works great is from Windy City Wire. www.windycitywire.com
Good pricing and the kicker, the wire is already marked for you. All you have to do is circle the room number, jack number, cable run, etc.. It saves a ton of time during trim out and final.
Pull at least
3 CAT5e or CAT6 to 2 locations in every room. Even if they are just buried in the wall for future use. Regardless if you plan on having A/V in that room or not. You will be amazed at how smart you will seem, even to yourself, 5 years from now.
6 Quad shield RG6 to each and every room. 2 locations if possible. 3 in heavily planned A/V locations.
16/4 speaker wire to every room and
16/4 into every ceiling. (backup in case 1 pair goes bad)
Try and use at least 2" conduit to allow for pulling additional wiring and even HDMI cables to shorter runs if possible.
And add conduit from the basement to all floors on both sides of the house. Even conduit into the concrete floors or crawl space, or floor joists. Just make sure there is a route up and down and side to side for anything you forget today, or comes along tomorrow.
And make sure you have dedicated circuits for your A/V, or even a seperate small breaker box for the circuits.
And 1 final note. Map everything you have pulled. Funny how our memory goes as we get older. You know it's funny how our memory goes as we get older.
