Sure. 'The Train to Grindelwald's Realm' is a great one. In this fanfiction, Harry boards the train not knowing it's a special one bound for Grindelwald's territory. He has to use his wits and magic to survive the journey and outwit Grindelwald's minions on the train.
One interesting story could be where Harry is on the Grindelwald train and discovers a hidden magical artifact. It leads him on an adventure to figure out its purpose and keep it from falling into the wrong hands.
One interesting fanfic could be where Grindelwald uses the train as a setting to test Harry's magical abilities. Maybe he creates illusions on the train to deceive Harry.
Dumbledore would be a great addition. Since he has a long history with Grindelwald, his presence could add a lot of depth and backstory to the fanfiction. Another good character could be Hermione. Her intelligence and knowledge of magic could help Harry in his encounters with Grindelwald. Also, Newt Scamander could be included. Given his experience with magical creatures and his own adventures in the wizarding world, he might be able to offer unique perspectives and assistance.
At first, it might be a relationship based on Grindelwald's self - serving motives. He sees Harry as a tool. But as they spend time together, there could be moments of mutual understanding. Harry might start to see Grindelwald not just as a villain but as someone with complex ideas.
In some fanfictions, it might be possible for Harry Potter to be depicted as the heir of Grindelwald. Fanfiction allows for a lot of creative interpretations. However, this goes against the original canon where there is no such indication.
Well, it depends on what you consider 'good'. Some people might like the ones that focus on Harry's internal struggle while being trained by Grindelwald. For example, there could be fanfictions where Harry has to decide whether to follow Grindelwald's teachings or stick to his own values. However, not all such fanfictions are well - written. Some might have plot holes or out - of - character moments.
One great 'Harry Grindelwald Fanfiction' is 'The Lost Tales of Grindelwald'. It delves deep into his backstory and his early days at Durmstrang. The character development in it is quite engaging.

For example, if the writer wants to show Harry as an even more powerful wizard than in the original series, they can give him the strength to take on Grindelwald and win.
