It depends on the methods choosen by the providers. If they agree on a few common types it would make things more simple. Take classic PPPoE for example. Since PPP supports the transport of multiple protocols PPP can transport also IPv6 in parallel with IPv4. But you could also use a second PPPoE session for IPv6.
Another issue will be IPv4, i.e. the lack of addresses. That's going to reverse the current situation. Youl'll have native IPv6 but IPv4 is tunnelled. One strategy is to tunnel IPv4 to the provider's NAT platform which will share public IPv4 addresses.

There are DHCP, SLAAC and a combination of both. If the provider gives a cheatsheet to Joe, he might be able to follow that and configure his router. Haven't seen much providers doing that. For DTAG VoIP I had to reverse engineer their VoIP gateway address plan to be able to create a secure config for my SIP gateway. Very professional ;-(

Native IPv6 comes with a /48 or /56 for the LAN(s) and a /64 for the transfer network. And the next marketing hype is IoT (Internet of Things) which I wouldn't place in my normal LAN.
