Searching for the perfect FAQ Accordion & Tab Plugin

Hi – Several years ago I purchased a Joomla! (ouch, the ‘J’ word!) extension called JU Tabs. It has some functionality that I am trying to (relatively) easily reproduce in WordPress. I have searched many sites, and checked many demos, but I have yet to find the perfect WP plugin to do what I want.

There is an example of the functionality I am after here: http://demo.joomultra.com/extensions/ju-tabs.html, if you scroll all the way to the bottom and look at the ‘Nested Tabs’ demo, and then pick the ‘Accordion in tab’ tab. This is the functionality I am looking for.

Can anyone direct me to where such a plugin exists? Free or paid? If it has to be linked with a page builder, we are using Elementor Pro. Although I would prefer it to be standalone, if possible.

Thanks in advance for any help!
