One great 'Harry Frees Grindelwald' fanfiction is 'The Unlikely Alliance'. It shows an interesting dynamic between the two characters where Harry's modern sensibilities clash and then gradually blend with Grindelwald's more archaic views.
I really like the fanfiction 'Harry's Quest to Redeem Grindelwald'. In this story, Harry uses his empathy and understanding to try and free Grindelwald from his dark past. It delves deep into their characters, exploring how they could interact in a world post - Voldemort, with Harry taking on the role of a healer of sorts for Grindelwald's damaged soul. It's a long and engaging read that really makes you think about the nature of redemption and forgiveness.
There's a fanfic called 'Freedom for Grindelwald'. It's a shorter piece but still quite good. It has Harry realizing that Grindelwald may not be as irredeemable as everyone thinks. Harry uses his knowledge of magic and his own moral compass to start the process of freeing Grindelwald from his prison, both physical and mental.
