As someone who has programmed for a living and now teaches programming for a living, I think Java is probably the best choice of the three languages if you want to balance ease of getting started and the most widely applicable learning. That said, the difference is a marginal one at best.

For instance, I find that students who come to my class having done FLL and knowing the LV based programming are a little slower at implementing their first programs than the kids who have programmed Ardiunos in C. On the other hand, when we get to the first big (meaning more than one class interacting) project, the kids who know LV style graphical programming go much faster. Yes this is probably in large part because they have to design the project on paper first (using a slimmed down UML style diagram). But if they had to do a large project in the vaunted "real world" they would likely be required to document their planning first. The LV-knowing students also are better at understanding how interrupted program flow works, because they have seen it laid out in front of them.

As Alan pointed out, not every problem is a nail. But when you are carrying around a hammer you tend to evaluate every problem as though it is a nail. Or to assume that problems that clearly aren't nails are some sort of weird exception.
