The Scorm Cloud thing might serve you well, but I don't think it is free to host your content there. You should look into it, but I'm pretty sure you'll find they want you to upload your content to their server, for a fee.
Canvas has limited support for TinCan. You might be able to hook Captivate content into that. You won't get all the data that SCORM spits out, only a tiny, tiny bit of it, like, I'm guessing, a single grade and a duration. The other thing people have tried to do is convent to Common Cartridge, which Canvas supports. The problem with common cartridge is that while it will run your content fine, it won't capture the answers to individual questions as they are answered during your mod. Instead, the quiz questions end up in a stand-alone Canvas quiz that has been stripped of the surrounding content. You can have students take the quiz, but it's really not the same as having their in-context answers captured. I've heard that the conversion is non-trivial, which comes as no surprise. I have not tried this myself.
Good luck, and if you find a happy solution, please let us know.
