[Star Wars] If Yoda can lift an X Wing and size doesn’t matter, why can’t Darth Vader crush entire cruisers the way he force chokes? Why can’t Emp Palps throw stars?

Yoda was exaggerating a bit in that instant (and also referencing the size difference between himself and Luke).

The reason is because the force takes immense focus and effort. Also because as luke says, it's not a power Jedi have. It's an energy field, and moving something with the force is sort of like "asking" the force to move it.
