I'm so lost trying to add a force towards the nearest collder with tag "x"

I want my player to be able to get an impulse towards the nearest gameobject with a specific tag, I'm a bit new to unity so probably parts of my code are no-sense, I know that I have to put all my wanted objects in an array and then calculate the nearest object every frame, please help, I'm lost:

 using UnityEngine;
 using System.Linq;
 
 public class PlayerAbilities : MonoBehaviour
 {
     public static PlayerAbilities instance;
 
     private Collider2D[] Gatherables;
     private GameObject[] GatherablesObjects = GameObject.FindGameObjectsWithTag("Gatherable");
     
     private float[] distance;
     private float nearestCollider;
     
     private Rigidbody2D rb;
 
     public LayerMask whatCanGrab;
 
     public float areaOfEffect;
     public float effectForce;
 
     private void Start()
     { 
         foreach (var collider in GatherablesObjects)
         {
             Gatherables = GetComponents<Collider2D>();
         }
 
         rb = GetComponent<Rigidbody2D>();
     }
 
     private void Update()
     {
         for (int i = 0; i < Gatherables.Length; i++)
         {
             distance[i] = Vector2.Distance(transform.position, Gatherables[i].transform.position);
         }
 
         nearestCollider = NearestCollider();
     }
 
     public void GrabDash()
     {
         if (Physics2D.OverlapCircle(transform.position, areaOfEffect, whatCanGrab))
         {
             rb.AddForce(new Vector2(nearestCollider) * effectForce, ForceMode2D.Impulse);
         }
     }
 
     private void OnDrawGizmos()
     {
         //Gizmos.DrawLine(transform.position, Gatherables[].transform.position);
     }
 
     private float NearestCollider()
     {
         return distance.Min();
     }
 }

Let me know all what you think of my code and how can I improve it please and thanks.
