A house should be comfortable first.
Here are some things I suggest
-Double paned windows, soundproofing the outside walls (or possibly the walls around your offices/bedroom)
-Air filtration, humidity, and temperature control (vastly underrated for overall comfortabiliy of house)
-Heated toilet seats (trust me, you won't ever want to go back)
If all your comfort needs are already met, then here are my "fun" suggestions:
-Swimming pool
-Theatre room with projector, lazyboys, badass sound system of some sort
-Computer Closet with extender cables for monitor / peripherals routed out of it (no noise from fans is nice)
I wouldn't hardwire any cables, but having a conduit system is nice. Once you have it installed between your offices and computer closet, you can just pull the cables you need with a fish tape.
