alt Hacker NewsEver ran a single mode bidi fibre in a conduit? Push a wire puller, cleave and terminate ends, done. Zero effort unlike pulling a jacketed CAT7 cable, zero worries from electrical interference too, future proofing up to 40GBps. I ran double strands in my house so in case one breaks, there's another.
The floors where native fibre is not needed have a cheap ethernet media converter from fs.com, everything else (3 floor switches) are interconnected with 10Gbps SFP+ modules and 2.5G ethernet for the hosts.
All done thanks to the great https://michael.stapelberg.ch/posts/2020-08-09-fiber-link-ho...

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.)
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.
