Does the eMMC version allow installing an NVMe drive?
Yes, the only hardware difference between the different version is really only the screen and the drive it comes with. You can technically buy the 64GB version and replace the screen with an anti-glare one at a later date, as it can be bought as a spare part for not much.
Personally I got the 64GB some time ago and am still happy enough with just an SD-card with good speed and decent size. I suspect that will change down the line, but right now I'm happy.
Oh and the carrying/storage case it comes with seems to be different for the 512GB version. Not sure about the 256GB version though.
I feel like they'll upgrade the chipset in 1-3 years with newer PCIe versions, then it will be worth the upgrade for you.
Personally I just got an anti-glare screen protector and called it a day
