Ooh, this is an interesting question... much to think about... Jesse's life and upbringing would honestly be much sadder and bleaker. He would still have his obsessive, anxious attachment and destructively submissive nature, and being a woman would just make him more vulnerable to exploitation and abuse. She would experience the same neglect from her mother, and abuse and degradation from her father that would come in slightly different forms. Still a similar overall impact, though. A female Jesse would end up in sex work, I think. Jesse's already terrible relationship with sex and damaging sexual practices would be amplified tenfold as a woman with the added circumstance of sex-based subjugation and the way that young girls in Jesse's position are especially preyed upon. She would be a very sad case, I think.... I'm feeling sorrow for the hypothetical girl-Jess as I'm typing this.

Shockingly, I don't think Max's upbringing would be hugely different. Max's dad (ol' Baz Mulligan), despite his rampant misogyny, would still have an attachment to his daughter following being left by Max's mum. He is highly unstable and gets angry when rejected — the need to have his child as a sort of friend and protégé would still be there, and Max would still want to follow after and appease her dad. There would be an absence of that "be a man" upbringing, but he would still be trying to toughen 'er up and teach her his ways with violence and crime and scamming and the likes. The biggest differences, I think, would be Baz being more controlling and slut-shamey to her. Her personal decisions would come under more scrutiny from him as a woman, and he'd place more rules upon her.
