I repeat:
Just because a port is physically & electrically USB-C doesn't mean it's logically USB-C. There are many phones 'out in the wild' wired USB-C but only transfer @ 480 Mbps (USB 2.0).
A UPS would still use Type-A, USB 2.0, for example. A SSD or NVMe with a 10 Gbps chassis will never reach more than 293.75 MBs, real world, best case because of the 2.35 GbE. 300 MBs is Serial ATA Revision 2 speeds (3.0 Gbps).
SATA II was standardized twenty-one (21) years ago.
Have you factored in the draw of your AP? The Certa (GL-AR750) draws 5W (5V, 1A) < 4W per its advertised specs. They're still in retail channels if one hunts around.
