My main use case is vertical, through-floor runs. I know it's penetrating a fire barrier (e.g. normal flooring OSB), so should probably have some sort of break... but what's typically used there? Common recommendation seems to be "in-wall-rated whatever", but I'd rather do it right if I'm taking the time to do it.
