I’m no expert tuner by any means but here’s my take. Narrow band only contains info on whether it’s rich or lean. Wideband is just what it sounds like, can read very lean to very rich. This is what’s needed to tune properly as your getting the actual AFR and not just data from the narrow band which is a lean/rich condition.
