I'm struggling to see the case for fibre-optic in a home. Cat 6 cable supports 10 Gigabits; 4k TV requires less than 50 Megabits. We obviously can't predict the future, but is it really worth spending over £1k for bandwidth you may never use, when £100 will comfortably give you 10-100 times as much as you're likely to be able to use in the next few years?
If you're that worried, put it all in conduit with mouse lines. That way, it's easy to upgrade later (if you ever need to).
