You just need to fetch the position in Update or LateUpdate method, don't do that in Awake or Start.

void Update()
{
    if(transform.hasChanged)
        myPosition = ((RectTransform)transform).anchoredPosition;
}

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/UIAutoLayout.html

The rebuild will not happen immediately, but at the end of the current frame, just before rendering happens.

According to the documentation above, you cannot freely trigger layout rebuild, so this way is just based on the order of layout calculations: Call these 4 methods before fetching the position.

// VerticalLayoutGroup vlg;
vlg.CalculateLayoutInputHorizontal();
vlg.SetLayoutHorizontal();
vlg.CalculateLayoutInputVertical();
vlg.SetLayoutVertical();
myPosition = ((RectTransform)transform).anchoredPosition;
