Question re bringing fibre into network

[FlashSA]

So the fibre gets installed into a home with a CPE box. LAN cable is then run from the CPE to the WAN port on a router.

My question: if my router WAN port is plugged into a switch and the CPE is plugged into the same switch, will they find each other as if I had connected them directly with a cat cable?

They would technically, but you are at risk of creating a loop. Why would you want to do it this way?

Is there a reason you would want to do this or trying to do something. Theoretically yes, but not sure about the use case...

Location C and B link into Location A. Location A also has the fibre CPE termination box. I want to use the WAN port on the router in Location B to handle the fibre connection and also be the DHCP.

So Location A does not need wifi?

Location A is a garage - no wifi needed

A 3 piece mesh system might be better. Cat6 cables to the satellites would help with the speeds in the different parts of the house.
