The winds and sand aren't mechanically very strong - the Martian atmosphere isn't dense enough to transmit much force even at high wind speeds. The only real dangers are obscuring the sun (important because Ingenuity runs on solar power) and getting dust in all kinds of places. But the landing site is pretty low latitude, and it's early in northern hemisphere spring right now, so power shouldn't be a problem.
Mars isn't quite as dead as the Moon, but still - you would be surprised how well things are preserved on dead rocks. As long as you can withstand the radiation and the cold, of course.
But the helicopter will, indeed, be expected to survive on its own, not even landing back near the river.
