Yes.

No. The parent is supposed to use their best judgment about what is best for the kid given the kid's reasonable long-term preferences [1]--not the parent's preferences. Or, to put it another way, what is best for the actual kid, not what would be best for the parents if they were in the kid's position. The two are often very different.
[1] I say "reasonable long-term preferences" to make it clear that I am not saying parents should indulge a kid's preferences for sugary foods instead of nutritious ones, lots of TV instead of a better mix of intellectual activities, and no exercise. I'm talking about cases where the adult the kid will grow up to be will genuinely say they are different from the parents in this respect and wish their preferences as a kid had been respected.

Most parents act in the best interest of a kid, not themselves. The outcome varies because parents model of the world usually flawed in many ways and they actually make bad decision thinking they have made good ones. E.g. my friend is obsessed with pre-school development. This is likely because she perceive herself as not smart and wants her son to be smart. She force her son to exercise, he can read and do some math at the age of 3. Long term this is bad for the kid. Unfortunately she cannot realize this. Doing so would require a level of knowledge and self-awareness she does not have. I her eyes she makes perfect decisions.
Why? I was exercising, reading, and doing some (very simple) math at age 3, and I turned out ok.
