I am trying to develop a custom module where I have options to select 4 different Joomla articles.

In my module XML file, I have the following:

    <field name="articleOne"
        type="sql"
        label="Select an article"
        query="SELECT id AS value, title AS articleOne FROM #__content"
    />

I can get this to output in the frontend, which is loading the ID. But how can I output the title, introtext and image?
