Best way to sell Articulate Rise course

I searched for learndash from within WordPress but did not find it, however, when I searched the internet I did find it at https://www.learndash.com. It is a premium wordpress pluin that works with most modern wordpress themes. They have three pricing options which  can be found at https://www.learndash.com/pricing-and-purchase/.  From $159 for a single site license to $329 for unlimited site license, but they have special pricing right now, so you may want to check it out. They do not have a free trail period, but they may be willing to refund if it doesn't work for you but you better read the fine print on that.   Hope this helps.  But you are still limited by the 2MB file size limit that WordPress imposes, ugh.
