[C#] Accelerate then decelerate to its wanted position

I have an object that needs to accelerate towards a location then decelerate to a given position using velocity's.

Here's what I have.

 //Movement
     public float decelDist;
     public float distanceTo;
     protected virtual void Movement() //Called from FixedUpdate
     {
         
         float adjustedAccel;
         adjustedAccel = acceleration / rigidbody.mass;
 
         decelDist = ((new Vector3(Velocity.x * Velocity.x, 0, Velocity.z * Velocity.z)) / (2 * adjustedAccel)).magnitude;
         distanceTo = Vector3.Distance(transform.position, wantedPos);
         
         if(decelDist >= Vector3.Distance(transform.position, wantedPos))
          {
             //slow down
             Velocity -= (wantedPos - transform.position).normalized * adjustedAccel;
             Debug.Log("slow down");
         }
         else if (decelDist < Vector3.Distance(transform.position, wantedPos))
         {    
             Velocity += (wantedPos - transform.position).normalized * adjustedAccel;
             Debug.Log("speed up");
         }                
     }

In my mind this seems like it should work, however, it clearly doesn't. it has an tendency to overshoot, then head back, overshoot a lot (1/4 of stating distance ish) again, and repeat.

It does have to use that Velocity variable because other things will be effecting it later on.

Thank you, for all the help!
