Which OMP route is selected if it was learned from the same Cisco SD-WAN device at location S4406T9E02F15?

The origin metric is used earlier in the OMP best path algorithm to differentiate between routes learned from different sources, but not for routes from the same device.

The OMP best path algorithm has multiple steps for selecting routes. If multiple OMP routes for the same prefix are learned from the same Cisco SD-WAN device, the tie-breaker is to select the route with the higher OMP route preference value.

The router ID is used as a tie-breaker later in the OMP best path algorithm, typically when comparing routes from different TLOCs or different WAN Edge routers, not specifically for multiple routes from the same device with the same preference.

Administrative distance is primarily used in traditional routing for comparing routes from different routing protocols, not as a direct OMP best path attribute for routes learned from the same SD-WAN device.
