Best way to determine if unit is actually moving right now for showing animation?

Beginner Questions
#1

Right now I try this
if ((Mathf.Abs(velocity2D.x) > 0.5) || (Mathf.Abs(velocity2D.y) > 0.5)),
but not sure if this is the correct one.
The goal is to set a moving animation, which I do with
animator.SetBool("moving", true);
and then handle this property in the Animator component

#2

I’d recommend velocity2D.magnitude > 0.5 or something similar.
