There's a fanfic where Harry, after the war, decides to make amends for the way wizards have treated goblins. He teams up with Hermione to learn more about goblin culture and starts a sort of cultural exchange program. It shows Harry's growth and his understanding that all magical beings should be treated equally. I can't recall the exact name, but it's out there and worth looking for.
One interesting fanfiction could be 'The Goblin's Friend'. In this story, Harry realizes the importance of the goblins in the wizarding world and starts to befriend them. He helps them with some of their rights issues in Gringotts. It's a really good read if you like this concept.
One possible fanfic could be one where goblins in the Harry Potter universe use their magical skills to build rockets. Maybe they are trying to find a new magical realm or escape from some dark force. However, I haven't actually read such a specific fanfic. You could try searching on popular fanfic websites like FanFiction.net or Archive of Our Own.
One interesting fanfiction could be where Vernon has a change of heart towards Harry due to some magical event that makes him see the wizarding world in a new light. Maybe a spell goes wrong and he experiences a day in Harry's shoes, which makes him more empathetic.
Another element is the reaction of the wizarding world. If Harry is nice to goblins, how do other wizards and witches react? Some might be against it, thinking that goblins are inferior, while others might support Harry. This creates a lot of conflict and drama in the fanfiction. In a story I read, Harry faced a lot of opposition from the Ministry when he tried to give goblins more rights in the wizarding economy.
Yes, there are likely some fanfictions with that theme. You can try searching on fanfiction websites like Archive of Our Own or FanFiction.net. There are many creative fans who might explore the idea of Harry Potter being a friend to goblins, perhaps delving into different plotlines and character interactions that didn't occur in the original books.
Well, it might start with Harry Potter getting into a real pickle. For example, he could be framed for a crime he didn't commit and on the run from the Ministry of Magic. The goblins, who have their own agenda and a sense of justice, decide to help him. They might hide him in their Gringotts vaults or use their magic to create a diversion. It could also be that the goblins are repaying a debt to Harry, or they see a greater threat that Harry's survival can help to prevent in the wizarding world.
One great fanfiction is 'The Unexpected Bond'. In this story, Harry and Draco are forced to work together on a project, and they gradually discover they have more in common than they thought.

There's 'Harry Potter: The Married Years'.

There's a fanfic where Ron betrays Harry for fame. It's called 'The Broken Bond'. The story delves deep into how Ron's jealousy and the allure of being in the spotlight drive him to make a pact with some dark wizards against Harry. It's a great read as it explores the complex nature of friendship and how easily it can be broken in the wizarding world.
There's a fanfic called 'Ginny's Precious Burden'. In this one, Ginny's pregnancy is not without challenges. She has to deal with some magical mishaps related to her condition.
