You should set up and run #NAT64 + #DNS64 in you #dualstack environment. Benefits are that it allows #IPv6 only devices a way to connect to IPv4 only servers, and provides valuable experience with IPv6, with no downsides. It does mean that dual stack devices will use NAT64 instead of NAT44, but you are still using NAT either way (and IPv4 devices always have to use NAT). See my article for more details and network diagrams https://sgryphon.gamertheory.net/2022/12/14/running-nat64-in-a-dual-stack-network/
