consider usb type C instead of micro-B
This is just a random idea. I don't know how USB-C receptacles actually are in terms of mechanical stability (e.g. THT of shield for mechanical mounting, but SMT for the data pins), ...
Both micro-B (3) and USB-C allow for 5V/3A power to be consumed even without any USB-PD (power delivery) related circuitry.
Maybe we get a few connector samples and look at them
