It isn't super harmful to occasionally use the full capacity for longer road-trip type situations, but it is indeed slightly better for long-term (100k+ mile) battery health to keep it in the 10-80% range most of the time. But it's also not a big deal if you constantly use 0-100%; it'll just be ballpark ~10% degraded at 100k miles.
