One great 'harry x tom animagus fanfiction' is 'The Animagus Bond' on Fanfiction.net. It has an interesting plot where Harry discovers he's an animagus and his form has a special connection to Tom. The story is well - written with great character development.
The appeal comes from the fact that it's a departure from the more common portrayals of Harry and Tom. The panther animagus concept opens up new avenues for character growth and relationship development. It can also be a way to explore themes of identity. Harry might struggle with his identity as a panther animagus and how that fits into his relationship with Tom. This internal conflict can make for very engaging reading.
One idea could be that the female character is a new student at Hogwarts who discovers Harry's phoenix animagus form by accident. She could be initially scared but then grows to understand and support Harry. Maybe she has her own special magical ability that complements Harry's, like being able to communicate with magical creatures too. This could lead to a series of adventures where they work together to protect the school from a new dark threat.
In many fanfics, Harry being a Dragon Animagus can bring about really cool storylines. For example, it could add a whole new layer of power to his character. He might be able to use the strength and abilities of a dragon in battles against Voldemort and his Death Eaters. It also could change his relationships with other characters. Some might be in awe of his new form, while others could be afraid.
One common theme is redemption. Tom, often portrayed as a villain in the original story, may seek redemption through his relationship with Harry. For example, in some fics, Tom realizes the error of his ways with Harry's influence.

I'm not sure of a specific title, but in general, in such a fanfiction, it would be interesting to see how Harry's new form affects his connection to the original Fawkes. Maybe there could be a story where the female Fawkes character helps Harry understand his new identity better, like teaching him unique phoenix abilities.
One possible fanfiction idea could be that in this relationship, Tom initially hides his dark tendencies. Harry, being abused in his past life, is vulnerable. Tom might use mind games on Harry, which Harry slowly realizes. But his love for Tom makes him conflicted. Eventually, he decides to break free and find his own strength.
