For regular folks there isn't much benefit tbh. Mainly I think it simplifies ISP architecture and offers slightly faster (like 10%) performance but ISPs have to support IPv4 stack for foreseeable future anyway so kinda moot point. If you game a lot p2p (i don't) you should, in theory, see lower lag.
For me personally, I work on networking startup so I'd like to be able to run IPv6 stack from my home network to test things.
Most video games don't work with ipv6 at all, which is ironic since in theory they're the exact use case for it
If you don't currently have IPv6 service, have you looked into something like Hurricane Electric's IPv6 tunnel broker? [0] It's how I got my first IPv6 subnet, and worked really well for me. I stopped using it when Comcast finally got around to providing IPv6 for non-business accounts.

It’s been like two decades since i last used this but at the time HE 6in4 tunnel required static ipv4
It has also been about that long since I used the service. According to my very, very distant memory this requirement was implemented by having you punch in your IPv4 address into a form to configure their end of the tunnel. I know for an absolute fact that Comcast was not providing me with a static IPv4 address, and the HE.net tunnel worked just fine.
