Suppressed selective fire weapons are useful for sentry neutralization (dog, armed lookout who resists, etc.), plus if the area under assault is large, unsuppressed weapons fire will alert other potential felons who can flee or prepare resistance.
Additionally, there is reduced chance of hearing damage and vision impairment, especially when the weapon is discharged in a confined space.
I've seen suppressed 10 and 77/22s advertised as effective in taking out lights (porch, hallway, etc).
