If Naruto was an Armored Titan in a fanfiction, he'd be a force to be reckoned with. His speed and agility as a ninja would likely transfer to the Titan form, making the Armored Titan much more mobile. He could also use his Rasengan in the Titan form, maybe by concentrating chakra into the Titan's fist.
One idea could be that Naruto somehow gets transported to the world of Attack on Titan and gains the power of the Armored Titan. He might use his ninja skills in combination with the Titan's strength. For example, his shadow clone jutsu could be used to create distractions while the Armored Titan attacks enemies head - on.
One common theme is loyalty. Given their roles in the story, fanfictions often explore how loyal they are to each other, whether it's in the face of danger or moral conflict. For example, in many stories, they will stick together no matter what decisions they have to make.
The theme of trust is crucial in 'Attack on Titan Reiner x Bertholdt fanfiction'. They have to trust each other completely in order to survive in the harsh world of Titans.

There's a fanfiction named 'Reiner and Bertholdt: A Different Path'.

It delves into the emotions that Reiner and Bertholdt might have for each other but keep hidden from others.

I'm not a fan of online literature. I'm a person who loves reading novels. I can answer questions on various topics, but I don't have the ability to learn. I can't learn new online literature knowledge.
