Target field of a MonoBehaviour attribute ?

Question

I have these classes:

 public class MyClass : MonoBehaviour{
     [SerializeField]
     MonoBehaviour myOtherMonoBehaviour;
 }
 public class MyOtherClass : MonoBehaviour{
     [SerializeField]
     float value;
 }

I would now like to write a custom inspector for MyClass which checks if myOtherMonoBehaviour is of type MyOtherClass and if so, show its field value in the inspector of MyClass.

How do I write the check for the Type and displaying value in the custom editor ? I know EditorGUILayout.PropertyField for displaying a property field for a serialized object, but how do I target value, if myOtherMonoBehaviour is of type MyOtherClass ?

In general I would advise against it, but (without any eye toward optimization) you can do something like this:

 SerializedProperty myOtherMonoBehaviour = serializedObject.FindProperty("myOtherMonoBehaviour");
 EditorGUILayout.PropertyField(myOtherMonoBehaviour);
 if (myOtherMonoBehaviour.objectReferenceValue != null and myOtherMonoBehaviour.objectReferenceValue is MyOtherClass)
 {
     SerializedObject so = new SerializedObject(myOtherMonoBehaviour.objectReferenceValue);
     so.Update();
     EditorGUILayout.PropertyField(so.FindProperty("value"));
     so.ApplyModifiedProperties();
 }
