Buy whatever you want, but as a standard 3’ is fine. My desk is cable managed properly and the powerbar is mounted under my desk. You can use zipties or 3M tape, and if you’re worried about aesthetics 1) if you do it correctly then it’ll be nice and 2) you’d already be the kind of person to use individual wall outlets for everything so yea I doubt it worries you that bad.
