Homepage Cache Slow to Refresh

I’m using a custom front page on my website, wherein I’m using a number of custom WP queries to display my latest site content in different sections.

I notice that with the caching enabled, logged-out users often see outdated content on the homepage as much as 2-3 hours after new content was posted. I’m wondering if the homepage cache isn’t refreshing itself when the new content is posted because the plugin thinks that the homepage is just a normal static page.

For the moment I’ve turned off caching on the homepage to avoid this problem but I would like to be able to serve the homepage from cache. What do I need to do to make sure that its cache gets rebuilt when new content gets published on the site?
