> If you're wiring a home today, I would 100% use OS2 over CatN unless you also need PoE.

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:

There is zero reason whatsoever to use OM over OS. The PHYs are only like $5 cheaper and it's worse in every way.

Multimode fibre is expensive, and quicky dying.

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.
