How is the route metric computed for usb network interfaces?

[John Roll]

I have 2 usb interfaces.  The enx* interface is a cell connection and wlx* is wifi.  It looks like the route metrics are causing all the traffic to go through the cell modem?

 

Where is the route metric configured and how can I change these in a general way?  I'd like to configure several computers without having to know the unique name of each interface.
 

route -n

There is a bunch of posts about how to to name your interfaces permanently.
