None. If you care about the screen, put a protector over it.
Absolutely... ZERO materials I have used over the years... since 2015 Macbooks... up to M1, has been able to protect the screen at all. And mind... I have Zeiss lens wipes (both types), microfiber clothes, heck, even the Apple cloth that I had to pay a hefty price for.
ALL of my Macbooks since 2015 have had the display scratched. Save with the exception of the current M2 Macbook Air that I have a screen protector on. ALL of the other ones have been scratched or have had staingate after just one year of use.
Again, if you care about the screen, either don't wipe it or just put a screen protector on.
