CAT7 is not the future. They used this monstrosity on a couple yachts I was working on, specifically becasue the lead EE considered the shielding important. Halfway through it was decided that the CAT7 would never certify at anything but 100mbit and be very intermittent. (Because of the shielding the EE considered no issue running in the same chase as KW SSB circuits, multiple KW power cables, phone circuits and a whole lot of other crap). They pulled it all out at great expense and used CAT6a and a lot of it in its own new set of runs. (In all likelihood the issue was improper installation, including kinking, bends, and ground problems systemwide)
CAT7 is likely not going to see much widespread use. 7a is promising though. THough I suspect that fiber is going to play a bigger role in horizontal and premises cable than it does right now.
If I were wiring a house right now it'd be CAT6a.
