I do see some scenarios where i've benefited from the 1Gbps -> 10Gbps upgrade:
- backups (wired) - I needed to make a local backup and it was more convenient to do over the network; backup speed did indeed nearly double; and it would further speed up if/when I'd parallelise it to two drives; I could have used 2.5Gbps on the backup server, but since it had SFP+...
- backups (wireless) - when TimeMachine backups wired Mac I've seen noticeable improvement over 10Gbps; I suspect when I move to faster WiFi (and 2.5Gbps+ connected APs) backups for wireless Macs would improve.
So even in regular households there are some bulk data transfers which can benefit from 2.5Gbps/10Gbps upgrade, some.
Yet another example are laptop migrations, though those happen less often than backups
