My wife has similar challenges, and is comfortable with her Mustang inflatable. We got the rings for tethering, it just made sense, even if we didn't need them at the moment.
Previously, when we got her a vest for the Hobie, we went to a kayak outfitter who suggested the models that would work best for her. Of course those were non-inflatable.
