        if (!is_string($collectionOrUrl)) {

The condition is_string($collectionOrUrl) is always true.

            throw new \InvalidArgumentException('$collectionOrUrl was not a string');
        }

        $this->collection = (new Client($collectionOrUrl))->selectDatabase($db)->selectCollection($collection);

It seems like $db can also be of type null; however, parameter $databaseName of MongoDB\Client::selectDatabase() does only seem to accept string, maybe add an additional type check?
