What you want is something called a WAN failover. There’s a bunch of routers that offer it but I know OPNsense (and pfsense) has it. The static IP address does not matter (to a certain extent since you have a double NAT and some router disable this by default for safety reasons). The WAN failover is usually defined by the NIC so you would say you want eno0 is primary, eno1 as secondary, and eno2 as tertiary which correspond to physical ports on the router.
If you want something plug and play, look at Firewalla. I haven’t used it but I heard that it’s so easy “even your parents can set it up”.

First place my mind went for a recommendation - and then discarded for someone w/ their exp level.
I would guess they could set up a pfSense box. Netgate has pretty good online docs. But even after deploying pfSense for 15 years, I still approach CARP (WAN failover) with some trepidation. It doesn't always just go (or stay going).

I haven’t heard of Firewalla but I’ve used UniFi products. The UniFi Dream Machine Pro can do WAN failover.

New to me too. It sounds promising.
