A possible plot point could be that Snape has a secret mission that is crucial for the wizarding world's future, but he is about to be discovered and killed by Voldemort's forces. Harry, through his connection with the magical world and his selfless nature, senses this. He then decides that sacrificing himself is the only way to ensure Snape can complete the mission. Harry's sacrifice could also lead to a change in the attitude of the wizarding community towards Snape, as they now understand the importance of Harry's act and Snape's role in the grand plan.
One key plot point could be the revelation that Snape is in some sort of danger that only Harry's sacrifice can prevent. Maybe it's a curse placed on Snape by Voldemort that can only be broken if Harry gives his life. Another point could be Harry's decision - making process. He would have to grapple with leaving his loved ones behind. And finally, the moment of sacrifice itself, which could be a very emotional and magical scene.
In the fanfic, it could be that Fleur is in a situation where she has to perform a dangerous task to save the wizarding world, like going into an ancient and deadly magical place. Harry, realizing the importance of her mission and also having deep feelings for her (maybe a secret love), sacrifices his own safety by going with her and ultimately giving his life to ensure she can complete the task and save everyone.
The plot might start with Snape realizing that Harry is in need of a proper family. So he decides to adopt him. As the story progresses, they would need to adjust to living together. Snape would have to change his living quarters to accommodate Harry. There could be a lot of emotional moments like when Snape tells Harry stories about his mother. Also, the fanfic could explore how Snape helps Harry deal with his fame in a different way than the Dursleys did. He could teach Harry to be more humble and use his fame for good in the wizarding community.
One key plot point could be the moment when Snape first shows a sign of not hating Harry. Maybe it's during a dangerous situation where Snape protects Harry instead of being cold towards him.
Well, it could be that Naruto sacrifices himself to seal away a dark and ancient curse that is threatening to destroy not only the ninja world but all of existence. He realizes that his unique connection to the tailed beasts and his strong willpower make him the only one who can perform this self - sacrificing sealing jutsu. So, he says his goodbyes to his friends, family, and the village he loves and gives up his life to save everyone.
Well, one interesting plot point could be how Harry manages to learn magic on his own without proper guidance. He might have to figure out spells through trial and error, which could lead to some really unique magical mishaps. For example, he could accidentally turn his owl into a strange hybrid creature while trying to perform a simple levitation spell on it. Another aspect could be his relationship with the wizarding world. Since he's raising himself, he might have a different view of Hogwarts and the Ministry of Magic compared to the original story. He could be more distrustful and independent, which would change the dynamics when he finally does interact with other wizards.

Well, the interracial relationship aspect is quite significant. It brought new dynamics to the royal family. Their wedding was a huge global event, but then the issues started. The lack of support they felt from the royal establishment against the media attacks was a big deal. And of course, their move to the US and their attempts to build a new life and brand there, like their deal with Netflix to tell their story, are all key points in their real story.
