NAT66 does exist and over time more software and hardware will support it. But you don't need NAT if you are using ULA; instead you would configure each system with both its ULA address and the global address from your provider (SLAAC can advertise multiple prefixes). Traffic to other internal systems would use the ULA addresses, while traffic to the Internet would use the global address.
