Yes, I'm following the H5P for Moodle project on Github: https://github.com/h5p/h5p-moodle-plugin I think it's currently in alpha and there are some issues with cron not working but I've tested it out and the basics are in place.
It's a SCORM, Articulate, Captivate, Raptivity, and other rapid elearning IDEs style set of activity and presentation templates (Check out the list of templates here: https://github.com/h5p ) but without the restrictions of SCORM and everything's integrated with Moodle.
There's also a more mature, public release H5P plugin for Wordpress. You can export activities from Wordpress and import them to Moodle, so they're truly shareable resources.
H5P project website: https://h5p.org/
And as Mike has pointed out, core Moodle has a lot of activities and features with authoring tools built in: https://docs.moodle.org/30/en/Activities as well as many more in the plugins database, currently 292 plugins: https://moodle.org/plugins/browse.php?list=category&id=1
I hope this helps
