I'm a real person, and I'm deeply concerned by a) the way Chrome is trying to become the de-facto "standard" for web apps and bully or dare the other major browsers into following suit or being seen as "out of date", and b) the level of access Chrome is trying to give to itself and web apps running in it. Google is already very clearly exercising its market dominance in search and other areas to try to gain ever more of our attention and data.

I'm insufficiently informed about the differences between File System Access API and Origin Private File Access to have an opinion on which of those I think is a better choice, but please remember that Your Experiences Are Not Universal.
