How to make my function only search for objects in the same axis? Code included...

Question

I need help only looking for the objects that are on the same height as me. Nothing below or above me. Thanks and here:

     public Transform GetNearestTaggedObject() {
  
         var nearestDistanceSqr = Mathf.Infinity;
         var taggedGameObjects = GameObject.FindGameObjectsWithTag("cover"); 
         Transform nearestObj = null;
         
         foreach (var obj in taggedGameObjects) {
             var objectPos = obj.transform.position;
             var distanceSqr = (objectPos - transform.position).sqrMagnitude;
  
             if (distanceSqr < nearestDistanceSqr) {
                 nearestObj = obj.transform;
                 nearestDistanceSqr = distanceSqr;
             }
         }
         return nearestObj;
     }

   var heightDistance = Mathf.Abs(objectPos.y - transform.positon.y);
   var closeInHeight = (heightDistance < SOME_SMALL_NUMBER);

   public Transform GetNearestTaggedObject() {
 
     var nearestDistanceSqr = Mathf.Infinity;
     var taggedGameObjects = GameObject.FindGameObjectsWithTag("cover"); 
     Transform nearestObj = null;
 
     foreach (var obj in taggedGameObjects) {
         var objectPos = obj.transform.position;
          var heightDistance = Mathf.Abs(objectPos.y - transform.positon.y);
          var closeInHeight = (heightDistance < 0.1f); //Adjust as necessary
 
         if (closeInHeight) {
             nearestObj = obj.transform;
             var distanceSqr = (objectPos - transform.position).sqrMagnitude;
             if(distanceSqr < nearestDistanceSqr)
             {
                  nearestDistanceSqr = distanceSqr;
                  nearestObj = obj;
            }
         }
     }
     return nearestObj;
 }

That will find the nearest enemy that is close in height.
