This is exactly what I did last summer. 10Gb fiber backbone between big switches, copper fans out from those to devices. I don't really need that much bandwidth but it's nice to have transfer faster than spinning rust write speed between my primary and backup storage servers.
For what it's worth, my reasoning had more to do with line noise and lightning isolation than bandwidth. I'm connecting between multiple "buildings" (two sides of my duplex-ish house and my shed) via buried 2" PVC conduit. Fiber means I don't have to worry about ground loops or static charge or lightning-induced faults.
