If your walls are ripped open, then sure run some OS2 everywhere, but Cat 6A gets you 10GbE at 100m, but even 'only' Cat 5e or (plain) 6 gets you that speed up to 55m (per 802.3an):

Why the need for faffing about with media convertors, at least with-in your domicile? (Fibre outside / to the garage certainly makes sense.)

For all the benefits I mentioned above, plus no electrostatic shielding required, and all fibers end in a CRS310-8G+2S+IN.

The issue with this setup is that you need an extra switch with an SFP+ uplink or media converter in each room or place where Ethernet will be used. And then you still need Ethernet cables anyway for the end devices. I can't justify this complexity for 40Gbps when I can now get 10Gbps inexpensively and conveniently.

Each floor's fiber terminates in a CRS310-8G+2S+IN except where I mentioned, there's a single 1G media converter.

Well, if you live in a multistorey house, each floor can be interconnected by bidi fiber, then you simply run ethernet to the end points.
