Best Carousel Shortcode Plugins

I’m looking to use a short code to build a carousel that uses random posts within a specific category, say “In-the-zone,” and that would 3 columns and then I’ll want to do four or five rows of these for each category. First is this possible? Second, what is the best plugin for this? I was looking at ‘Styles with Shortcodes‘ as an option and tat seems to be a very robust plugin, but are their other options that might be free?
