For me, it was for a nearly 100ft run that try as I may to get a good termination, I'd often find my Mac Studio and Ubiquiti EdgeSwitch struggle to negotiate at more than 5gbps. So I got a smaller switch upstairs, ran 10GbE to it, approximately 10ft, and then ran OM-3 fiber for the 100ft up into my attic, across my house and down into the garage. Rock solid at 10 Gbps.
