I should also think about possible chapters if it's a series, but maybe start with a standalone story. Avoid clichés as much as possible, but some tropes are okay for children's stories.
Potential plot points: Introduction to the world of kids fighting, the protagonist's motivation (e.g., to protect friends, prove themselves, win a prize), encounters with mentors or rivals, training montage with challenges, setbacks that test their resolve, final battle with a twist, and resolution where characters have grown. kidsfighting.com
Either approach works. I'll need to flesh out one of these ideas into a full story. Let me go with the first fantasy example as it allows for more imaginative elements. Ensure that the story is engaging, has clear stakes, and positive messages. I should also think about possible chapters if

Using their combined powers—Alex’s water to cool the lava, Kai’s fire to deflect attacks, Lila’s air vortices to disrupt Viper’s energy flow, and Bruno’s earth-moving to destabilize the core—the team frees the trapped Council members and shatters the Cabal’s hold on Eldoria. Either approach works
I should decide on the tone. Is it comedic, serious, adventurous? Probably adventurous with some action scenes. Need to ensure the story is appropriate for kids, so no overly violent content. Focus on the challenges and strategies rather than graphic fights.
