Rayleigh would be a great candidate. He's an experienced pirate and has already trained Luffy for a while. He has a lot of knowledge about the world of pirates and could give Luffy a talk about the deeper secrets of the Grand Line or how to deal with the powerful enemies that lie ahead.
It could be about Luffy having an important conversation. Maybe it's about his dreams, his crew, or some kind of revelation he has. Without reading it, it's hard to say exactly.
Well, 'Luffy and Ace: Unbreakable Ties' is a fanfiction that I really like. It focuses on their childhood memories and how those shaped their relationship as they grew up. There's also 'Ace and Luffy's Great Escape' which is full of action. It shows their cleverness in getting out of difficult situations. 'Luffy and Ace: The True Friendship' is a must - read too. It simply and effectively shows the depth of their friendship.
In Luffy fanfiction, Shanks might talk about his hopes for Luffy's future as a pirate. He could mention how he saw the potential in Luffy when he gave him the straw hat.
Another interesting 'yamato x ace fanfic' is 'Yamato's Encounter with Ace'. This fic starts with Yamato's first encounter with Ace.

One great 'Ace Protective of Luffy' fanfiction is 'The Unbreakable Bond'. In this fic, Ace is always on high alert to protect Luffy from any threats in the New World. He uses his fire powers in really creative ways to fend off enemies.
Yes, there are quite a few. Some might focus on female Luffy's adventures alongside Ace in the One Piece world, exploring their unique bond and how they support each other in the face of challenges. These fanfictions can offer new perspectives on the characters and their relationships.
Well, one characteristic could be the focus on a more 'romantic' or 'intimate' relationship between Luffy and Ace, which is often not in line with the original platonic nature of their bond in the source material. However, this is a very controversial aspect as it goes against the typical portrayal of their brotherly relationship.
Character development is key. Fanfictions explore how Ace and Luffy grow under Garp's influence. Maybe Luffy becomes more disciplined in some stories, or Ace learns to be more open - hearted, all thanks to their interactions with Garp and each other.
