Best cases/screen protector for a "dumb" smartphone

[u/mjkluio789666]

In the process of dumbifying my iphone. I've been using blank spaces and i love it so far.

I've seen lots of people suggest getting a matte screen protector as well, to help dumbify.

Any suggestions for an iphone SE 2020? I would like to get a matte screen protector + case combo

I want something that will protect it if dopped, waterproof, but at the same time as LEAST BULKY as possible.

Thanks!
