Edit: The AJAX call is done via com_ajax:

...
async loadData() {
        let requestString = this.prepareRequest();
        const res = await fetch(requestString);
        if (res.ok) {
            let parsed = await res.json();
            if (parsed.data && parsed.data.length > 0) {
                this.data = parsed.data;
            }
        }
        return this.data;
    }

    prepareRequest() {
        if (!this.checkConfiguration()) return;
        let requestString = 'index.php?option=com_ajax&module=' + this.moduleName + '&method=' + this.method + '&format=json';
        if (this.backendModule) {
            requestString = 'administrator/' + requestString;
        }
        requestString += '&limit=' + this.limit + '&page=' + this.page;
        return requestString;
    }

    checkConfiguration() {
        return !!(this.moduleName && this.method);
    }

Get Joomla Articles via Model inside static (Module) Method

When calling an AJAX Method in a Module Helper file the method has to be static. I have no app context there, when doing the following:

public static function getDataAjax()
    {
        $data   = ExampleHelper::getJArticles();
        return $data;
    }

public static function getJArticles(){
        $app = Joomla\CMS\Factory::getApplication();
        $model = $app->bootComponent('com_content')->getMVCFactory()->createModel('Articles', 'Site', ['ignore_request' => true]);
        $articles = $model->getItems();
        return $articles;
}

An error 500 got thrown: Call to a member function get() on null

#0 /Users/MyUser/Sites/joomla5.site/libraries/src/MVC/Model/ListModel.php(222): Joomla\Component\Content\Site\Model\ArticlesModel->getListQuery()

#1/Users/MyUser/Sites/joomla5.site/libraries/src/MVC/Model/ListModel.php(271): Joomla\CMS\MVC\Model\ListModel->_getListQuery()

#2 /Users/MyUser/Sites/joomla5.site/components/com_content/src/Model/ArticlesModel.php(651)...

There is a similar question here (about getting articles in the backend) (Link) but as far as i can see the solution there does not help me.

I would like to use the model rather then doing my own database query here...
