In thinking about a new home, I would look at industry and how wiring and water runs are done. See if you can have a wiring closet.
If a new technology arrives that requires fibre, or requires 12 volt distribution, I would certainly plan that new wiring could be done without having to break ceilings, or walls, other than at outlets.
And I would have a 200amp 220v entrance, (which is what I have in my home), and with today's technology, protection devices for lightning caused voltage surges and the like. I would get a few 1k watt UPS's and some car batteries and build a backup system in case of power loss that could cause freezer or fridge content loss. And I would look at a dual internet system one of which has vpn only access to a second system, Reserve this system for automation. You should be able to vpn from the www to check on the internal system.
And I would not overdo the spending. You still want to be able to live and to enjoy stress free living.
