Resolution matters a lot for productivity, and Meta's displays have more than twice the number of pixels. Image quality for the display will be much better on the Meta VR glasses because of the lack of interference from outside light. See-through displays sound good in theory but require too many compromises IMO. There's no such thing as "black" on a see-through display, only "transparent". Definitely try before you buy.

I feel like Meta's track record of VR device support has been decent enough. Quest Pro still gets updates even though it was discontinued almost two years ago. When they ended support for Oculus Go they released an update that unlocked the device and granted root access. I'm sure you can find some complaints on Reddit but looking at what they've actually done I think it looks pretty good.
