Well, in many fanfictions, there's an original character who is a dragon - slayer with a new type of dragon magic. This character is usually very popular as they add a new dynamic to the existing dragon - slayer group in Fairy Tail. Then there's the character who is a lost princess from a forgotten kingdom, but she has extremely powerful magic that she doesn't know how to control at first. Also, there's an original character who is a master of illusion magic, which he uses to deceive the villains and help the Fairy Tail guild in their battles.
Popular original characters in Fairy Tail fanfiction can vary a lot. There could be a character who is half - human, half - demon, and struggles with his identity. He has a special power that is a combination of demonic and human magic, which makes him both feared and respected. Another is a young girl who was raised by spirits and can communicate with them easily. Her connection to the spirit world gives her an edge in battles as she can call upon the spirits for help. There's also the character who was exiled from his own magic tribe for having a different view on magic, and he brings new and revolutionary ideas to the Fairy Tail guild.
Well, in some fanfictions, a plot twist might be that the Fairy Tail guild is actually an experiment by an ancient and powerful magic user. So all the members unknowingly have a special connection to a greater power. Another cool twist is when a character's magic completely changes. Like Gray who suddenly has fire magic instead of ice magic due to some dark magic curse. Also, there are fanfictions where the main villain is a doppelganger of one of the main characters, which creates a lot of confusion and interesting scenarios.
Lucy is a very popular choice. Since she lives at Fairy Hills, there are a lot of possibilities for stories centered around her daily life there, her relationships with the other girls, and how she continues to grow as a mage.
Natsu is often a very popular character in Fairy Tail Empire fanfiction. His powerful fire magic and his brash but endearing personality make him a great protagonist in many stories.

Her relationship with the spirits could also change, like some spirits becoming more powerful mounts for her.

Lucy is also popular as she has a lot of room for different interpretations in baby form, like her celestial spirit keys and how they might interact with a baby Lucy.
Often, the main kitten characters themselves are quite popular. Their innocent yet brave personalities make them stand out. Also, characters like Natsu might be popular as he could interact with the kittens in fun ways, like trying to teach them how to breathe fire (in a comical way of course).
