For Star Wars Fallen Order fanfiction, a great plot could be Cal getting stranded on a strange planet filled with dark side energy. He has to find a way to resist the dark side while also finding a means to repair his ship and escape. Maybe he discovers a lost tribe of beings who have an ancient knowledge of the Force that could help him in his fight against the Empire. He would then have to decide whether to trust these new beings or not.
A plot could involve Merrin forming an unexpected alliance with a group of smugglers. Together, they navigate through the dangerous underworld of the Star Wars universe while Merrin also tries to hide her true identity as a Nightsister. This would lead to many tense and humorous situations as she tries to fit in with this new group while also dealing with her own personal growth in the Force.
The plot mainly follows the journey of Cal Kestis. He's a young Jedi trying to survive in a galaxy where the Jedi Order has been decimated. He embarks on a quest to rediscover his Jedi powers and also uncovers secrets about the past while being hunted by the Empire.
Maybe the Sith Order decides to change their ways. In the fanfiction, the Sith could start to question their age - old pursuit of power through domination. They might form an alliance with some Jedi who also see the flaws in their respective orders. Together, they create a new order that aims to govern the galaxy in a more just and equal way, with a new understanding of the Force that doesn't divide it into light and dark but rather sees it as a whole with different manifestations.

One plot idea could be that Fives manages to spread the word about Order 66 more widely before being silenced. This could lead to a split in the clone army, with some clones defying the order.

Another plot could involve Ahsoka finding other Jedi who managed to escape Order 66 and them teaming up to figure out how to deal with this new threat from the clones and the Sith behind it.

One idea could be a crossover with the Star Wars Rebels universe. Cal Kestis could team up with Ezra Bridger.
