> who often rely on their default modem/router setup from their provider - let's say inbound 443 is open,
That's not a great assumption to start with.
1. Routers normally come with no inbound possible.
2. Some ISP will require you to opt into accepting 443 at all.
3. It will be open on the router for one specific device - there's no realistic scenario where your home router is configured to allow 443 to any internal address. (Unless you do that explicitly)
