 The documentation is not correct about this function running after awake. It does by default, but not if you specify a load type:

 Providing no load type defaults to RuntimeInitializeLoadType.AfterSceneLoad, running the function after Awake.
+Other versions that have been verified to also use this exact order:
+  * 2021.1.12f1 (editor only)
+Methods with RuntimeInitializeLoadType.AfterSceneLoad, or RuntimeInitializeLoadType.BeforeSceneLoad will only be called for the **first** scene in a run of the application, not every scene. ((Tested in Unity 2019.4.19f1, in editor and in Android build))
+Another important thing is that the method should be static!
+----
+===== Other Nuanced Info =====
+If you create a GameObject and attach a MonoBehaviour to it in "BeforeSceneLoad", or another early LoadType, the Awake function of that MonoBehavior WILL be called at the point of creating the GameObject. In other words, the Awake will be called earlier than the Awakes of GameObjects in Loaded((tested in 2021.1.15f1)).
+Example:
+<code cs>
+[RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSceneLoad)]
+static void AutoRun() {
+	GameObject obj = new GameObject("New Object", typeof(SomeMonoClass)); // Awake of SomeMonoClass will be called here
+}
+</code>
+----
+[[https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager-sceneLoaded.html|SceneManager.sceneLoaded]] event subscribers will be called before ''AfterSceneLoad''. By the name of the event, you might assume that the event is called **after** the scene was loaded, but it appears to be called just before. ((tested in 2021.1.15f1))
