Hi there -- So, let me start off with tempered glass screen protectors DO NOT work with the fingerprint sensor on the Note 10 Plus. Neither do the cases with built in screen protectors. If you are concerned with scratches, your phone should already have a plastic screen protector installed (you can check for it around the hole punch camera). I have a Galaxy S10, but the fingerprint sensor is about the same as the one you find on the new Note series. This fingerprint reader uses sound waves to read your fingerprint. Many tempered glass screen protectors do not lie entirely flush with the phone's screen so it messes with the accuracy of the fingerprint reader. If you peeled off the plastic screen protector already, I know Samsung is selling them for 30 bucks, but I think any PLASTIC screen protector should work fine. It's unfortunate that glass screen protectors aren't compatible, but it is what it is. I think your phone screen (Gorilla Glass 6) should be hard enough to handle a few falls though.
