There were opportunities to cast Little Red and her Granny or Jack and his Mother as people of color. No reason why not. They just didn't. It may not be a "shame," but it's a "disappointment," at least to me.
As for going younger with both Jack and (especially) Little Red, I think it's fine. The more I think about someone like Sophia Grace (who is a bit cartoonish and over-the-top) going toe-to-toe with crazy Johnny Depp, playing one of his crazy Johnny Depp roles as the Wolf, it will probably be very funny and anything but "sexual," which I'm sure will sit well with Disney.
As for her "knowing things now," you can lose a bit of your innocence without losing your virginity. She's become "streetwise," just a bit.
She "know things now" also doesn't imply that she's "done things now."
It almost (but not quite) guarantees the removal of any sexual overtones or tensions in that scene with the Wolf.
And I'll bet you they screen tested together (Depp and Sophia Grace), just to see how it would come off before they made their decision.
