Another idea is Naruto helping Gaara control his tailed beast better. Naruto, having a tailed beast of his own, could share his techniques and experiences. He might take Gaara to a secluded place where they can practice without any distractions. This would not only strengthen Gaara's control but also deepen their bond as they face similar challenges.
One plot idea could be that Naruto realizes his love for Gaara during a joint mission.

One plot idea could be that Gaara and Sakura are on a joint mission in a foreign land. They have to rely on each other's skills. Gaara's sand control and Sakura's medical ninjutsu and brute strength can complement each other.

Then they continue the mission together and form a deep friendship along the way.
