I couldn't find a case that meets all my requirements so I had to compromise and go with the Amardillo: https://www.amazon.com/dp/B07VT2NZZR/ref=cm_sw_r_other_apa_i_yZbxEbZ67VY8H

However, this one doesn't cover the full edge as your requirement. If you don't worry much about the Spen hole, I think Ghostek is better for your needs: https://www.amazon.com/dp/B07VJJKPMS/ref=cm_sw_r_other_apa_i_M4bxEbHXG10FA

I asked them and they confirmed the edges are raised enough to cover the screen. But the Spen hole is cut too wide from my opinion so I didn't choose this.

Or you can choose some 360 cases if you don't mind the front cover may reduce a bit of display quality.

im using the spigen liquid air case. i used a slightly bulkier and more protective ghostek for my Note 10+ for almost the whole year and i absolutely loved it. I ended up switching to the spigen for the sleek, thin feel and I've been really enjoying it, so i picked it up for my N20U also.

Im also planning on getting the AmFilm tempered glass protectors. supposedly they protect just as well as whitestone, with some alleging it's better. it's also slightly cheaper and comes with a second set of installation materials, including another protector.
