Don't discount wireless as most people need that for the increasing number of portable devices we have. You won't be wanting to wander around plugging little devices into the wall.
You can still locate the ONT where you would later put a distribution centre if you decide to do that later. Personally, I wouldn't rush into the full cabling at this stage. That can be done at anytime if you decide it is desirable.
As an example of a low cost setup, my fibre comes in from the street via my road facing garage. The Chorus guys routed the cable to a full height under-floor area of the house and installed the ONT there. From the ONT I ran an ethernet cable through the wall to the supplied modem/router in my rumpus room. This room is where my main computers are and where my old ADSL modem/router was sited.
There is an ethernet cable from the router going upstairs through the floor to the TV corner. That cable has a wireless AP on it giving upstairs wireless coverage and cable outlets.
I gave a lot of thought as to where the ONT should be sited but, at the end of the day, it has to be connected with an ethernet cable and this can be any length up to 100 metres.
