But as time passes, he could come to see it as a new opportunity for growth, realizing that his strength doesn't solely rely on his physical form.

It could also introduce new characters. Maybe there's a healer or a wizard in the Land of Ooo who claims to be able to restore his arm. Finn would then go on a quest to find this character, meeting all sorts of strange and wonderful creatures along the way. And each encounter would be different because of his disability.
Maybe he was protecting someone in Wave. He's always the self - sacrificing type, so he could have put himself in harm's way to save a villager or a friend.
