Creatively, Gringotts can be a place of cultural exchange. Since it's a bank that serves both wizards and other magical creatures, it can be a place where different magical cultures interact. In a fanfic, Harry could witness a meeting between a goblin banker and a centaur who is trying to deposit some rare magical herbs as collateral for a loan. This could lead to all sorts of interesting storylines about cultural differences, misunderstandings and cooperation within the magical world.
One possible motive could be to stop Voldemort from getting his hands on some crucial dark magic item stored in Gringotts. Harry might think that by destroying it, he can prevent Voldemort from getting more power.
One possible implication could be that Harry has access to unlimited wealth and resources. This would change his status significantly within the wizarding world. He could use the gold to fund various projects, like improving Hogwarts or helping out the less fortunate wizarding families.
It could also be a strategic move. Gringotts is a highly secure place. By buying it, Harry could ensure the safety of important magical artifacts or secrets. He could use it as a base to store and protect things that are crucial for the future of the wizarding world, like ancient spells or prophecies.
In a Fem Harry Potter Gringotts fanfiction, she could be on a mission to steal something from her own vault. Since she's female, she might use her charm and wits in a different way than the original Harry. For example, she could pretend to be a damsel in distress to get past the goblins' security. This would add an interesting twist to the story as it subverts the typical male - hero - steals - item trope.
