In the original series, Naruto was oblivious to Hinata's feelings for a long time. In the fanfic, if he 'owns' her, he'd be much more aware. Their relationship would become more intimate right from the start. He'd probably show more concern for her well - being, not just as a friend or comrade but as someone he truly cares for romantically.
I don't think it's a super popular concept in the Naruto fanfiction community. There are so many directions fanfiction can take. Some focus on romance, others on battles or new powers. While Naruto's relation to Konoha is fundamental, the idea of him 'owning' it in fanfiction is not something that seems to be everywhere. That said, there may be some fanfictions out there that play with this idea, but compared to things like exploring Naruto's heritage or his growth as a ninja, it's probably not as prevalent.
In some Naruto fanfictions, Hinata could potentially be portrayed as a 'weapon' in a very metaphorical sense. For example, her Byakugan abilities might be exploited in unique ways that make her seem like a strategic weapon for a side or a cause. But in the canon Naruto story, she is a character with her own agency and not really a weapon.
One great source for Naruto and Hinata fanfiction could be FanFiction.net. You can search for stories specifically focused on their relationship there. There are often new and interesting takes on their story, from how they first fell in love to their married life in the future.
Perhaps in the fanfiction, Hinata wears a micro bikini for a special festival in the Hidden Leaf Village. Naruto is really excited to see her in it. They participate in the festival games together and Hinata's new look makes Naruto see her in a different light, more as a strong and confident woman.
One possible plotline could be a story where Naruto has to choose between two versions of Hinata, the original Hinata and a version from an alternate RTN (Road to Ninja) universe. Maybe in this fanfiction, the different Hinatas have unique abilities or personalities that make Naruto's choice more difficult.
Maybe he owns a ninja training academy as a business. Since he is a powerful ninja, he can pass on his skills and knowledge to the next generation. He could offer different levels of training courses for both beginners and more advanced students.
In many Naruto x Hinata Hyuga fanfictions, their relationship is often explored in greater depth. Usually, it emphasizes Hinata's long - standing admiration for Naruto. Her shy yet determined love for him is a central theme. Writers might show how Naruto gradually realizes Hinata's true feelings and how their relationship evolves from friends to something more romantic.
Another way is to join fanfiction communities or forums dedicated to Naruto. Ask the members for recommendations. They can point you to some great stories that don't involve any forced relationships. Some members might even have their own collections of fanfictions that they can share with you, which are often carefully curated and free of inappropriate content.
Sakura could be a common character. Since she has a history with Naruto, she might be part of the harem in some fanfictions. Also, Tenten could be included as she is another female ninja in the Naruto universe. And Ino, with her strong personality, could also be written into the harem scenario.
