I bought 4 cases so I thought I will share my experiences here:
1) Nillkin Camshield Pro - Love the idea (sliding cover over entire camera module), but the rest of the case is terrible. I used this case on my S21U but the hole is both too small and too deep to allow access to the S-pen on the S22 model, making it useless. Unless your fingers are the width of a pencil and you have long fingernails, good luck getting the S-pen out. Totally useless. Otherwise a very basic case, nothing special about build quality or protection level. Very uneven/wobbly if set on a flat surface or wireless charger as well.

2) Torras Shockproof - Great look & build quality, especially with the frosted back. Extremely slippery though, and drop protection is minimal. If you like a very slim minimalist cast, this is the best I have seen. Cutout is big enough to access the S-pen without issue. Way overpriced at $30 CAD.

3) Caseology Parallax - I think this is going to be the case I keep. Excellent build quality, great protection without being super bulky, and adds a little extra protection for the camera housing that other cases do not offer (between the lenses). S-pen cutout is extremely easy to access. Indents on back feel great on the fingertips and there is plenty of grip. Buttons feel great. Good price too.

4) Supcase Unicorn Beetle - Expensive and bulky, but top tier protection. Has a port cover for the USB-C charge port which is a feature I wish way more cases had. Portrait and landscape orientation kickstands are a nice touch.

A note on camera lens protectors - I am a professional photographer, and I have tried these lens protection products for my previous S21U as well. They provide the advertised protection from physical damage, but the issue with them is they flare like crazy - any time you introduce another layer of glass to a lens design (especially ultra cheap 'glass' used for these protectors) you increase reflections. On "real" cameras, that is why quality lens filters are made out of proper borosilicate glass and multicoated specifically for reflection reductions - obviously the the lens protectors that are made for pennies sold on Amazon are not using anything of the sort. I took them off my S21U after too many issues with flare - YMMV. Other than a case that provides a cover for the camera assembly though, you don't really have any other option for lens protection.
Hopefully that helps some of you folks!
