New to Design/Training and looking for a mentor

My 5cents is that plan the content so that anything basic, tracked quiz, untracked knowledge self assessment exercises , images, video and more ...  add that in rise. Good, quick work process.

What you need storyline for is the interactions that bridge from basic to advanced/custom or the interactive intensive parts. Then you add the storyline block to rise and still present your advanced storyline parts in rise. I choose to present with a "clean look so storyline player interface is customized to not be visible and seemlessly integrate with white rise pages, but this can vary from the purpose with the storyline block. I use full HD project sizes in Storyline, nothing less. Consider your users devices. Test the scaling.

Hint, via storyline you can add content from other authoring tools officially unsupported by Rise.

Using powerpoint for creating videos with or without narration, animated gif graphics or just plain graphics of any sort,  is also part of how you create content. So you have that already going for you! Powerpoint is now part of your content creation kit. Like Adobe suite etc..

But now and going forward, you present your content via rise and you learn to live with its limitations -  which by the way gets less annoying every year. :) Great improvements and feature enhancements always on the horizon.

So in summary you stay in rise and you use storyline blocks with storyline for anything out of the ordinary.

Hope this helps.
