The character of Candace was likely inspired by the idea of an older sister who is constantly frustrated with her younger siblings' antics. It's a common family dynamic that was exaggerated for comedic effect in the show.
Candace was probably inspired by the concept of an older sibling who feels responsible for keeping her younger brothers in line. Since the show is all about imagination and having fun with family relationships, they created Candace to be the voice of 'reason' (even if she's often wrong in her assumptions about Phineas and Ferb's activities). They took the typical older sister traits like bossiness and a sense of superiority over younger siblings and made her into a lovable character in the show. Also, the need to have a character that creates conflict in the story, as her attempts to bust her brothers drive a lot of the plot forward.
The creators of 'Phineas and Ferb' might have been inspired by different aspects of family life when creating Candace. Maybe they thought about how an older sister might feel when her younger brothers seem to get away with everything. Her character could also be a nod to the idea of an older sibling who is trying to grow up and be more 'adult - like' while still being a kid herself. Her constant efforts to expose her brothers' activities add an element of suspense and humor to the show. And perhaps they were also inspired by the idea of a character who has a vivid imagination of what her brothers are doing wrong, even if it's not really what it seems. This makes her a complex and interesting character in the show.
