Usually yes but in a lot of ways no and I don't think I can answer with any of the provided options.
I don't pick a class combination and then aim for that. But I commonly have a concept of what the character wants to be down the line. I certainly have never (rare one shots aside) started a low level mage that had no more specific goals than to eventually be a high level mage. And if some PClass fits the concept then I will certainly take that into account early on.
In real life I didn't know what my career would be when I was a kid. But I knew I wanted to take all the hard sciences I could in high school. And I knew I wanted to go to Ga Tech, not Savannah College of Art and Design. To me taking feats and assigning skill points are intertwined with the roleplay aspects of the character and not *just* mechanical selections. So taking a feat that is a class prereq need not be a check in a box To me it is simple to imagine that character knowing that he has to spend effort mastering whatever talent the feat represents in order to get to his ultimate goal.
And then on top of that, my goal for L12 can evolve a little or into something completely different at L6 than it was at L1. So I'm planning all the way, but I think I way outside the spirit of pre-set that is implied in the OP.
