Another emotional moment could be when Naruto discovers his father's dreams and hopes for him through some form of memory or message. If he sees that his father always believed in him and had great expectations, it can be both heart - warming and overwhelming for Naruto.
When Naruto finally realizes the sacrifices his father made for the village and for him. For example, learning that his father sealed the Nine - Tails inside him to save the village at the cost of his own life. This realization can be a very emotional moment as Naruto understands the depth of his father's love and selflessness.
