I don't think I can do that. OS of "Characters learn to let go of fears" or "Avoiding emotional pain/fears (or trying to protect oneself too much?) leaves characters feeling worse/more stifled than if they'd just faced them or acted in spite of them" seems incomplete and vague.
I think the OS characters are in denial that they are doing what they're doing out of insecurity.
One resists getting help for his senile loved one for fear of being forgotten if she sees other people, thus losing a last immediate family member, but keeping her isolated makes her hate him and act destructively, and he grows to resent her too since he'd rather go back to acting (although type-casting is a problem due to disability, frightening appearance, and popularity playing a horror character in some cheesy movies. Maybe IC wants to revive his career and ride his coattails and win him over by writing him a rom-com script since no one else would.) She's got delusions that she still owns a ranch and he's out to sabotage her, then MC shows up, is mistaken for a relative, and she gives her affection to him, inciting jealousy and an awkward Situation since MC is the only one who can calm her. The first character insists that he's just keeping her safe, but his motive is fear of losing his last connection to his family and setting into the despair that he he'll eventually lose everyone he loves. The correct response would be to realize this and get her the help she needs. Maybe she'll forget him, but it'll be far less stress on the both of them than fighting and resenting each other. The first character can find peace if he learns to appreciate her the way she is Presently, like MC does since they just met, instead of lamenting loss of who she was. That's just one strand in what I assume is an ensemble goal.
IC denies that he cares what his parents think of him, since they rejected him for dropping out of college, even though he'd love to get fame to make them come crawling back to apologize for being wrong) or whatever. He acts confident or cocky, but he's still bitter about it. His attempts to use MC as a springboard for attention backfire when people only pay attention to MC's extraordinariness. Affection turns to envy. That might be RS, or maybe MC's reliance on IC (Situation) is RS stuff.
MC wants to help others, build a new life in the present as a responsible, productive member of society (to feel worthy of love and happiness), and try new exciting things like fly in an "aeroplane", but he's held back by fears of failure based on past experience (Proven), Worry about potential disaster ("What if we crash?" "What if I choke during our song and it makes everyone laugh at us and I let IC down? I'd better hide rather than take that chance."), and just that awful visceral experience of anxiety. MC seeks external methods of anxiety management (avoidance, trying to win over someone to, in a way, possess as a shortcut to gain the courage and better life he doesn't believe he can earn on his own as he is-- something he lets go of at the end. IC is helping him with this goal, but I don't think it's THE Story Goal-- everyone has a stake I guess, or is affected by the efforts, but they've got their own issues, which is why I flip-flop between wondering if it's an ensemble goal or if I should narrow focus to everyone's concerned about MC finding a place in life or stuff he does interfering with their plans or whatever) when he should be facing his fears.
The dog-like monster, representing MC's unruly mind and resistance to change and joins the story after MC attempts a physical shortcut to fix his brain, fails obedience training, takes MC's savior complex (not "I'm Jesus" but "I see danger everywhere and must try my best to help or else I'm terrible!") to the extreme and starts sucking up people and animals to protect them from life's pain, which is unpleasant for them. MC will have small successes and failures as a tug of war between Worry and building Confidence thanks to IC's pushing, but after taking a risk of some kind leads to a large failure, echoing the traumatic one from his past that drove him to drop out of society, he wants to give up and join the monster so he'll never have to worry about failure and responsibility again. IC will somehow inspire him to not give up and make the now-kaiju-sized monster release everyone by communicating with it or taking control over it, and that involves facing fears somehow. Maybe he learned something from failure that allows him to succeed this time.
I guess that all points to an overall theme about how trying to insulate oneself/others from life's inevitable suffering (or risks?) just leads to more, which is hard to put a Story Goal to.
A giant pile of OS like that, which likely needs trimming, is why I need a formula like what you came up with for defining all three parts of a conflict. Knowing what I want to say and how will help me both generate ideas when stuck as well as trim the fat and keep on track.
I could say that "MC needs to realize that OCD/anxiety is a cycle that can only be broken through exposure" then he could use this realization to see how everyone is perpetuating their on misery in OS, but that seems like it could be an alternate illustration for the OS thing.
