OS2 is not needed for most homes. Use multi-mode fibre (OM4 or OM5), which can do 25-100 Gbps @100m (or more):

You'd have to have quite a house to need internal runs longer than 100m (300'). For runs up to 100m: 2.5 Gbps can be done with Cat5e, 5G with Cat6, and 10G with Cat6A:

I never seen it used outside North America.
The biggest reason to use multimode - cheaper equipment, is no longer here. High-end multimode NICs, and transmitters now cost more than SMF.
It would be future-proof but not present proof, as you likely don't have anything else than RJ45 plugs on your devices…
On the other hand, replacing a cable in a conduit by a fiber is a half-hour task (you just stick the fiber to the cable, then pull the fiber with the cable) so it's not really worth it to be future proof in this case. You'll only be saving a hundred bucks in cable by doing so.

Won't you end up with a bunch of media converters everywhere though?
Or if not - how should one think about deploying all this in a new home?
To give an example - OS2 single-mode fiber is the standard fiber for contemporary datacenter deployments and I assume also for last-mile deployments. It's super cheap (less than 20cpf for indoor cable, whereas cat7 copper is closer to 60cpf), has an insane range (a standard $25 fiber PHY can operate with a cable from 0m-10km), and has an insane bandwidth limit (it's currently used for everything from 1gbps to 400gbps).
If you're wiring a home today, I would 100% use OS2 over CatN unless you also need PoE.
