On the other hand (as a father of two) I find myself thinking about how my dad handled situations, comparing how I just handled it, and going, “wow did he have that backwards” haha. Not all the time of course and like you I have definitely come to appreciate how tough it is to make the “right” call, but we certainly have learned some things.
One thing Boomer parents were really bad about - at least in my experience - was building a healthy relationship with food and meals in general. So much punishment and reward centers around food, it’s quite upsetting when you really think about it.
I’ve had quite a few friends in my life - men and women - with eating disorders of all shapes and sizes. You can almost always find stories involving their parents at the core of them. Making everyone sit at the table until the last person has finished their plate, the old “starving children in Africa” line we’ve all heard at least secondhand, forcing toddlers to eat everything and then they get dessert as a direct reward (which often ignores teaching them how to read signs that they’re full). The list goes on.
