Get a list of Transforms in unity

I am trying to get a list of Transforms for a spawn system. I have tried to use GameObject.FindGameObjectsWithTag with an array instead of a list and it seems like the array needs to be GameObjects and not Transforms, since that's what it's looking for. I've also tried another piece of code, but it only returns one random Transform into a list, here it is:

public List<Transform> t;

void Start()
{
    t.Add(GameObject.FindWithTag("Spawn").transform);
}

As you can see in my code, it will only add one Transform to my list. I would like to add multiple Transforms instead of just one.

You can use Linq Select like

using System.Linq;

...

public List<Transform> t;

void Start()
{
    t = GameObject.FindGameObjectsWithTag("Spawn").Select(go => go.transform).ToList();
}

This basically somewhat equals doing

var array = GameObject.FindObjectsWithTag("Spawn");
t = new List<Transform>(array.Length);
foreach(var go in array)
{
    t.Add(go.transform);
}

Array of gameObject:

GameObject[] gos;
gos = GameObject.FindGameObjectsWithTag("Enemy");

To get the transform:

gos[0].transform

To make a list of transform:

public List<Transform> t;

foreach (GameObject go in gos)
{
   t.Add(go.transform);
}

public List<Transform> t;
public List<GameObject> go; //GameObjects where youl look for
 void Start()
 {
 for (int i = 0; i < go.Count; i++)
 {
    if (go[i].tag == "Spawn")
    {t.Add(go[i].transform);}
 }
 }

It might be simpler to add these "spawn" objects to the list at the time of their creation instead of trying to find them afterwards. Is that an option?

For example:

GameObject spawn = Instantiate(spawnObj);
t.Add(spawn.transform);
