The Flaw is the physical/psychological manifestation of the Wound. The Want is the stated action necessary to overcome the subconscious Need. So, the Wound creates the Flaw that drives the Want in order to satisfy the Need.
Example:
Wound: grows up poor (inciting situation)
Flaw: feels worthless (unconscious character motivation)
Want: to be somebody of note (plot)
Need: self-acceptance (subtext)
So, because the protagonist's backstory didn't allow them to get enough hugs or whatever as a kid, they act out in such a way, hoping it will heal the Wound, but it can't. What's done is done - they must learn to accept it. It's the Flaw that they can heal from. The plot then is about transitioning from absence to plenty, from worthlessness to self-acceptance.
Poor to rich.
Addict to clean.
Loner to family.
Criminal to cop.
Unloved to loved.
Ugly to beautiful.
Outcast to acceptance.
Underachiever to overachiever.
But it doesn't have to be that complicated. The Wound and the Flaw can be the same thing.
Example:
Flaw/Wound: kid grows up poor (inciting situation / character motivation)
Want: to be rich - to provide for loved ones (plot)
Need: seeks redemption (subtext)
Or even...
Flaw/Wound: kid grows up poor (inciting situation / character motivation)
Want/Need: to be rich - to provide for loved ones (plot - no subtext)
It's worth noting that the Flaw isn't usually subconscious. People know what they're about - but often refuse to confront, admit or otherwise deal with it, so there’s this illusion that it is 'subconscious'. (It's also why Therapy is a thing.) For example, an addict knows they're an addict, they just refuse to accept it. Achieving their Want gives them the strength, either directly on the page or through inference, to overcome their Flaw and reach a better place (self-acceptance/forgiveness/confidence) - whatever that means for the story – in order to deal with their Need.
The inciting incident kicks off the story. It's the change the creates momentum. The inciting situation is whatever it is about their backstory that creates their Flaw/Wound. For Batman it was the death of his parents. This is also what drives character motivation.
The important thing to remember is this can all be super light like Luke Skywalker or that Groundhog movie remake Palm Springs (recommended), or it can be uber-dark like Silence of the Lambs or The Godfather. There’s no right or wrong as to how much we explore or how deep we go.
eta: Generally speaking:
Wound - Conscious - they know they grew up poor
Flaw - Unconscious - they don't realize how it affected them
Want - Conscious - they know they never want to be poor again, so they work to be rich
Need - Unconscious - they don't understand why
