One way to make it interesting is by exploring the power dynamics. Since Naruto has the Kyuubi within him, the arranged marriage could be a political move by the village elders to control that power. For example, they might arrange a marriage with a powerful clan's member to ensure loyalty and the proper use of the Kyuubi's strength.
Another aspect could be the character development. Naruto might initially be against the arranged marriage as he values freedom in choosing a partner. But as he gets to know his arranged partner, he could learn about their own struggles and dreams, which in turn makes him more understanding and mature. This could also lead to a deeper bond between them that goes beyond the arranged nature of their relationship.
In such a fanfiction, a possible idea is the development of the relationship between Naruto and the female character. It might start off rocky due to the arranged nature. But as they get to know each other, they could discover each other's strengths. For example, Naruto's determination and the female character's unique skills could complement each other.
A potential plot twist could be that the arranged marriage was actually a ruse set up by an enemy. They might be planning to use the opportunity of the marriage to get closer to Naruto and somehow steal the Kyuubi's power.
Sakura could also be a candidate. Given her strong personality, she might initially resist the arranged marriage. But as she gets to know Naruto better and realizes the potential of the Kyuubi's power, she could warm up to the idea. Plus, it would create a lot of drama considering her previous relationship with Sasuke.
Naruto is very outgoing and extroverted. He loves being around people and making friends. Artemis, on the other hand, is more reserved and independent, used to living in seclusion with her huntresses. So Naruto might constantly try to include Artemis in social situations that she would rather avoid.
To write this fanfiction, think about the setting. Since it's in the Naruto universe, you can include elements like ninja training and village politics. You could have Naruto teaching Hana some of his unique jutsu, and in the process, they start to bond. Also, don't forget to add some conflict. For example, some of Naruto's friends might not understand why he's in an arranged marriage, and Hana might face criticism from her clan for getting involved with an outsider like Naruto.
Perhaps there could be a plot where the arranged marriage is a part of a prophecy. Naruto and Hanabi are destined to be together to bring a new era of peace and prosperity to the ninja world. At first, they both reject the idea as they have their own lives planned. But as strange events start to occur that seem related to the prophecy, they come together to figure things out and in the process, develop feelings for each other.
Another plot might involve the reactions of the other characters. Sasuke could be very against the idea at first, thinking Itachi doesn't deserve any form of happiness. But as he sees the positive changes in Itachi because of Naruto, he might start to accept it. Also, the village elders might have their own motives for arranging the marriage, like trying to create a stronger bond between the Uzumaki and Uchiha clans.
One interesting plot could be Naruto being initially hesitant about the arranged marriage but slowly realizing Hinata's amazing qualities. For example, he might start to notice how she's always been there for him in her own quiet way, like during his battles when she worried from afar. This could lead to a deeper connection between them as they get to know each other better in the context of the arranged marriage.
One possible interesting plot could be the initial resistance from both Naruto and Neji towards the arranged marriage. Naruto, being his free - spirited self, might not be too keen on the idea at first. Neji, with his strict upbringing, might also have reservations. But as they start to spend time together, they gradually discover each other's hidden depths and begin to develop feelings.
Perhaps in some fanfictions, the arranged marriage is part of a political move to strengthen the alliance between their clans. Naruto, being the hero of the village, has to accept it. Ino, on the other hand, tries to use her intelligence to find a way out but instead finds herself drawn to Naruto's determination and kind heart.
