Ive just checked a few iPhone 13 Pro Max screen protectors with my iPhone 14 Pro Max, and the only one which I found may be OK is the full screen Torras one where you don't have a cutout for the notch but it just has a small cutout at the top for the speaker, although noticed the speaker on the 14 seems to be marginally longer than that of the 13 so it may cover some of it.
