I've used the Whitestone Dome Glass Screen Protector as it adheres to the phone the best especially with a curved edges phone, it works well with the fingerprint scanner and the sPen.
It is on the whole case friendly.
The caveat is that it isn't cheap and for the first time buyer it can look daunting to fit.
It's available on amazon or Whitestone Dome Home Page.
They come as a pack of one or two.
I'm currently using the official tpu Samsung Screen Protector that works well with the fingerprint scanner and spen.
It adheres via using the applied fit guard and a squeegee.
It isn't expensive and comes in a pack of two.
The only caveat is don't let it get wet via rain as this can make the edges lift snd don't clean the phone with any liquied cleaner.
It is on the whole case friendly.
They are available on Samsung.com
Now there are loads of Screen protector ms available from different with sone being good and some nkt being so good.
I wouldn't recommend the Glass Screen Protectors that just have glue around it's four edges as these in my experience just tend to pop off.
Have a forum search here and look at YouTube for further information perhaps @Stanley j
