I am in the same boat as you. I took a few days to read the RFCs to figure it out (as I never found any sort of good guide for IPv6), and I am not confident I set up my hone network securely, mainly because of the "I don't know what I don't know."
I also had a few different subnets (to separate IoT and untrusted devices from my network), and I could never consistently get a stable subnet from my ISP outside of a /64 (mind you I am using Pfsense, not a consumer router). When did get a /56 subnet, I had a lot of connectivity issues I never had with only IPv4, and they went away instantly once I blocked all IPv6 off my network. I was also never able to confirm outside connectivity into my network via IPv6 either.
I may try it again, but I really don't want to go through a lot of pain and suffering to try and get IPv6 "working" to only have those connectivity issues again.
