The 'stranger in a new world' trope is quite common. The reader is often from our world and ends up in the Naruto universe, like in many stories where they have to adapt and Naruto helps them. Another is the 'enemies to lovers' trope. There are fanfics where the reader and Naruto start off on the wrong foot, maybe due to a misunderstanding, but then fall in love. And of course, the 'soulmate' trope where they are fated to be together.
The 'discovering - powers - together' trope can be found in some Naruto Uzumaki x Reader fanfictions. This is when the reader and Naruto are both exploring new powers or abilities and they support each other through the process. Another trope is 'reincarnation - love'. It's the idea that the reader and Naruto have some past life connection and are drawn to each other because of it. And the 'helping - Naruto - heal' trope, where the reader helps Naruto deal with his past traumas and in the process, they fall in love.
