finding mouse click coordinates

Question

hi, I'm trying to create an object where ever I click on the screen. I have a camera facing downwards (with global y axis going up through the camera) and I want to be able to add an object anywhere on x, z (later I want to add a control for the y axis). I've tried two different approaches

     if (Input.GetMouseButtonDown(0)) {
                 #region mouse position
                 Vector3 pz = Camera.main.ScreenToWorldPoint(Input.mousePosition);
                 pz.z = 0;
                 Debug.Log(pz);
                 #endregion
                 Instantiate(blah,  (pz), Quaternion.identity);

and this

 if (Input.GetMouseButtonDown(0)) {
                 #region mouse position
                 Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
                 Debug.DrawRay(ray.origin, ray.direction * 10, Color.yellow);
                 //Debug.Log(ray);
     
                 #endregion
     
                 //Instantiate(blah,  (pz), Quaternion.identity);
             }

on the first I'm getting the closest but I keep getting the cameras coordinate on the second I don't know how to make the raycast hit an entire plane. how can I get- in this case- the xz coordinates of where I am clicking at y = 0? and is ScreenPointToRay using and returning in its local coordinates?

public GameObject sfo; Vector3 mousePos_X() { var mousePos_ = Input.mousePosition; mousePos_.z = 10; Vector3 pos = Camera.main.ScreenToWorldPoint(mousePos_); return pos; }

 void Update()
 {
     if (Input.GetMouseButtonDown(0))
     {
         Instantiate(sfo, mousePos_X(), Quaternion.identity);
     }
 }
