>Red has nothing to do in the party once he’s gotten home.
>>grandpa told me to fuck off again and learn more about the world
Red is an actual child as far as the lifespan of his species is concerned and it's been established pretty clearly how highly he regards Bugenhagen's opinion so him being told to go out there and learn is about as in-character as it gets.
>Cid’s motivation is he has nothing better to do than go with the party
He's very clearly out for revenge against Shinra since they not only shut down the space program but then went onto try and steal the Bronco, are you dense?
>Vincent and Yuffie are literally missable
And despite this both have a reason for going after Shinra. Vincent even has a clear connection to the villain, establishing personal stakes.
Yuffie is out to Make Wutai Great Again because Shinra turned her country into a tourist trap.
Both of these character's identities are compromised and by extent defined by the losses they suffered at Shinra's hand which serve as their motivator. It's the main theme of the game.
>Cait Sith? What is this guy even doing here after getting the keystone
I suppose you missed the part where Reeve is/was the head of Urban Development and the company he worked for decided to not only destroy an entire sector of the project he's working on but then went onto say that they don't need to rebuild it. He's also there to fight Shinra and is unique from the rest of the main cast by virtue of it being revealed to him that yes, he is in fact, one of the baddies.
The story is genuinely not that complicated, I really wonder how people miss so much of it when it's presented to them in plain, written text. Either you quite literally did not read the story and cannot critique it or you're illiterate.
