It could make Naruto more curious about the Kyuubi from an early age. Since his mom was a fan, he might have grown up hearing stories about the Kyuubi that were different from the common view. This could lead him to be more open - minded when it comes to dealing with the Kyuubi's power within him.
If Naruto's mom was a Kyuubi fan in the fanfiction, it might mean that Naruto feels a stronger connection to the Kyuubi not just as a power source but also on an emotional level. He could be more determined to master the Kyuubi's power because he feels like it was something his mom believed in. He may also be more empathetic towards the Kyuubi, seeing it as something his mom respected rather than just a monster, which would be a huge step in his character development.
Well, in this fanfiction concept, Naruto may have a different view of his own identity. Knowing his mom was into the Kyuubi, he might see himself as having a special destiny related to it. This could drive him to constantly strive for better control of the Kyuubi's power. He could also be more confident in using it, as he would think that his mom's interest in the Kyuubi was a sign that there was something great and worthy about it. And this newfound confidence and sense of purpose would shape his character in a more positive and assertive way as he grows up.
