Mount is properly and your USB cable is going to be so short it won't matter if it's 3A or 5A as long as you make sure you're using a good quality cable.I have the same problem - running a Pi 5 off a 12V supply, though in my case it's a yacht racing instrument system, not a robot.
I also have a 5A buck converter: I have mounted it on a printed circuit board and added a USB C breakout board... Amazon sells many brands: then a USB C to USB C cable.
It's interesting that the USB C connectors and cables "officially" support only 3A, and a Pi 5 at max CPU supposedly consumes 28W (= 5.5A at 5V), but I suspect there is a big safely margin there, so it's probably OK.
It woud be really useful if someone could publish documentation so the cct board cound tell teh Pi 5 that it can produce the required 5 A
