Why is the half-life for first order reaction the only one that is independent of initial [A]?

The initial concentration just cancel each other out when the half life equation is being derived

This can be visually shown on a graph because in first order reaction, the time in-between one half reaction and the next is the exact same, the only thing changing would be the slope, or K.
