Reading more I think this is a “backpower” issue and, interestingly, everything seems to work fine without the USB hub. Do I really need a powered hub for an NVME drive? Any way I could get some kind of data corruption without one?
Could be. If your hub puts anything on the D+/D- pins it will confuse the PMIC and stop the Pi booting.
Regarding the 15W mentioned above, that isn't the applicable limit. That's what the recommended PSU can supply.
The limit for bus powered USB devices is 6W (1.2A @ 5V) and that's shared not per device.
