I was able to create what I wanted!

I was lucky to find this one, and with a little figuring I got what I wanted from my page. There are the native widgets to this plugin, as well as the original Woocommerce widgets, so with a combination of them, it’s looking good. I also used the Custom Product Tabs for WooCommerce plugin to expand my tabs, and this Builder plugin picked them up and put them to use as well. A little bit of CSS and I was able to make it all work. Very nice.
