In terms of “what little stuff” you might want, at times, I have found bug spray and some form of sun protection (I mostly rely on clothing like a long sleeve pullover fishing shirt and hat) to be highly valuable. Depends on where and when you paddle. I’ve really regretted not having bug spray handy when getting back to a ramp when the no-see-ums are out and swarming so now I carry it in a PFD pocket. You might also consider an inexpensive hi-viz item that you can wave around if in distress (e.g., a hunter orange bandana you could tie to your paddle and wave over your head to attract attention). As with the bug spray, I carry at least one item like that in a PFD pocket in case I were to become separated from my boat.
Although I do carry a paddle float, I personally find paddle float re-entries awkward and somewhat unreliable, even in benign conditions. They are less so in some boats (perhaps your Scorpio as the rear deck looks reasonably flat and with a notch behind the cockpit that would keep the paddle perpendicular to the long axis of the boat), more so in others. Lots of people will argue that being able to do a paddle float re-entry can give you a false sense of security (especially if you’ve only used them in non-emergency situations). The sooner you learn to roll (and then re-enter and roll), the better IMO. Get the paddle float though. If nothing else, they can be a pretty useful aid in learning to roll (but that’s another thread).
