If I were doing it today, I would add fiber along with copper. It is super thin and would fill in the cracks. What I've found in places I've lived in the past is that most cables are not used. Some are used. And some are heavily used. And every once in a while, things are moved around. Once I moved a server from inside to the garage. Once I did the opposite. It is nice to be able to take the heavily used trunk and hook up the fiber pair, and use the copper for everything else... and no planning. And be able to change your mind.
