Naruto's ability to empathize is a key trait. He could use this to understand Hanabi's struggles, whether it's about living up to the Hyuga family expectations or something else. Hanabi could show her perseverance. For instance, if she's training hard to improve her skills, Naruto would be there to support her, and together they could show how positive character traits can help in personal growth and in the betterment of the village.
