Even the basic spotlight search is pretty hard to discover. I'd say about half of the iPhone users I meet have never heard of the feature, and are surprised when I swipe down on their screen and show it to them. With iOS 16 though, they've finally added a button, so that should help on that front. Another feature that isn't well known is swiping between recent apps by swiping horizontally along the bottom of the screen. I didn't know about that feature until somebody posted about it on HN a while back.
