Viewing all phineas and ferb characters as autistic is so nice because you rarely see a range of personality types with autistic characters in the same show
Bless Bless Bless
Also let me help you back this up:
- Phineas and Ferb freaking out because someone broke their rutine (Bully Bromance Breakup episode)
- Phineas and Ferb's echolalia in "Candace against the Universe"
- Ferb having selective mutism and only chosing to speak when he has an interesting fact

Part 2
- Phineas being oblivious about Isabella's love indirects (that sinking feeling episode)( and most of the episodes too)
- Baljeet having a written schedule and hyperventilating when they do something it's not there (Bubble boys episode)
- Baljeet having a lof information about a specific subject (tip of the day episode)

Part 3
- Candace having an special interest/hyperfixation in Ducky Momo since she was a little girl to now into teenhood
- Candace can't break the routine to bust her brothers or she feels empty
I also HeadCanon she has ADHD as she is very loud and impulsive and can't focus on anything that doesn't has to do with busting her brothers, her boyfriend Jeremy, or Ducky momo

Where. Do . I. Begin
- I headcanon him with autism and ADHD as well.. First, he can't do simple things and chose to do it the complicated way.
- I mean, he flew the Big Ben to be close to his departamento so he didn't had to drive to the store and buy a watch
- In another occasion he made clones of himself so he didn't had to wait in the line to buy things
- He rambles.. A LOT
- Changes subject in the conversation too quick ,forget what he was talking about and is a bad listener. (Maybe that's why he gets along with Perry because he doesn't talk and Doof has freedom to lead the conversation)
- The 'a platypus?' 'Perry the platypus???' (prosopagnosia right there)
- The way he stands with his hand in this pose
- His happy stimming

Part 5
- Buford. He doesn't like the taste of two thing together. He prefers them separately
- Speaks a lot of languages and play a variety of instruments
Lawrence Fletcher:
- Pls he works at an antique store and is an history nerd
- The echolalia. Fossils dun dun dun
Also he in general. There's no doubt he is Ferb's father
I see Candace trying to bust her brothers as her being controlling as a mechanism for mitigating her anxiety. It's not just about her blindly sticking to that role for the sake of it. If everything goes the way it's "supposed to" then there will no unexpected disruptions that she doesn't know how to deal with.
There's also that indignation keenly felt by all eldest siblings, at how unfair it is that their younger siblings are treated much more leniently now that their parents have mellowed out and are much less uptight about policing their children now that they have enough experience as parents to realise how little of a big deal all their previous fretting was. Not inherently a neurodivergent thing, but it's a big part of her nevertheless.
Also, there's that thing I don't quite know how to put to words, where autistic girls tend to be much better at masking than autistic boys, and tend to be much more cognisant of the consequences of inadequate masking, and so she's so overpowered by cringe that she's compelled to police them at all times lest they call too much attention to themselves, which—in her opinion—is inherently risky to them and their safety, on top of being risky to her by 'blowing her cover'.
Also, that rigid adherence to making sure everybody 'follows the rules'. I've seen that in a lot of autistic girls before.
