God knows everything, so of course he would pick a woman who would want to do it, and just told her after picking her. Which still sounds weird by today's standarts.

Of course God knew she would have wanted to do it. But she still had to say "Yes". Otherwise God would have been forcing Mary to be impregnated without her consent.

I suppose my classes and Church were not Real 1992 Catholics enough.

I don't know what your point is. Go to any Catholic church and ask the priest - did Mary have a choice whether to become the Mother of Jesus or not - I know they will say "Yes, she did have a choice". We mediate on Mary's fiat in the Rosary. It's part of many homilies. It's not a new interpretation. It's not modern. It's right there in the Bible.
