Those are nice cases, but it's such a large phone that I decided to also get a Pop Socket Slide Stretch.
It's admittedly pricy, but it has made a world of difference in terms of my comfort holding my s22 ultra and being able to use it with one hand easily. Since it slides I can have it centered or I can slide it to the bottom and I slide it to new positions frequently depending upon the app I'm using and how my hand is feeling.
Edit to add... I also got this because I can slide it out of the way of my wireless charger, unlike other pop sockets.
