This is the most heavily loaded configuration I use with this device and
I don't have issues with either an NVMe SSD or GPU. No hardware-related
issues with any USB devices (data goes through PCIe in the end).

Maybe I should swap this card out for something else like Intel 8260 or
an upcoming 9260 to test out whether this is a PCIe issue but I don't
think it is.
Found this unanswered thread at infradead with the exact same hardware but a
different PCIe setup:
