Hey Scott,
You're good. If you see it in the fetch and render, you're seeing it as Googlebot sees it.
Google has had capabilities to crawl Ajax content for some time now. And while you don't see the content when you view source, that's not a big a problem. As long as the content is on the page at load Google should not have a problem indexing it. So after load, you should look in the Inspect Element section, that's how Google will see the content.
Where there may be crawlability issues is in content that requires user action to display. Google is inconsistent with how many actions they will attempt in order to index content.
