Welcome Hunter.
I am running into a similar issue with my stairs, luckily for me my wall happens to be against my garage and not an outside wall, So i am just putting drywall directly onto the concrete with the glue. From what I have gathered on this forum as well as talking with local building officials is that somethings just cannot be brought up to code. So any of your above options sound do able. With that being said make sure you get your beam properly sized if you choose to go that route.
In my basement I plan on letting the stairs hang out under the floor joist and installing my hand rail under there, so that I have the most amount of room for stepping on. Also depending on what is at the bottom of this stairs you may want to make your railing removable so that you can swing furniture down and around the corner easier.
