Grip recommendations?

So, this is by far the largest phone I will have ever owned and I have pretty small hands so I am looking into getting something that can attach to the back of a case and act as both a grip and kickstand. It doesnt need to allow wireless charging but if theres an option that works on a case and also allow wireless charging that would be good. I plan on going with Spigen Rugged armor or Liquid Air case.

I've looked into a bunch of things, Ring grips, popsockets, Samsungs silicon case (dont really want this) and magsafe case attachments. Do you have any recommendations for small hands users? Oh also I wouldnt want it to interfere with the S-pen functioning.
