I have the following code in a custom submit handler:

$status = \Drupal::messenger()->messagesByType('status');
foreach ($status as $delta) {
   // Here I want to extract the text string that is in $delta.
}

The variable $delta now contains this:

delta => stdClass Object
(
    [__CLASS__] => Drupal\Core\Render\Markup
    [string:protected] => Article request My article has been created.
)

How do I get the protected string from $delta?

I've already tried some methods, but so far I haven't found one that works.

Here are those tried so far:

Error: Call to undefined method Drupal\Core\Render\Markup::getMessages()
Error: Call to undefined method Drupal\Core\Render\Markup::toString()

A protected variable is only accessible from the class itself. Your only option to access it from outside the class is via a public method.

Looking at the Markup class, the only public methods are:

count()
jsonSerialize()
__toString()

Simply put, because Markup implements the magic method __toString() (which returns $this->string), you can get that string simply by using the object as a string, e.g. echo $my_markup_object;
