My ISP does this right (provides a /56 for routing), but unfortunately both are dynamic and change periodically. Every time I disconnect and reconnect from the internet, I get a different prefix.
I ended up needing to have ULAs for devices where I need to know the IPv6 address on my network (e.g. my internal DNS servers).
I use openwrt on my home network which uses dnsmasq for dhcp. It can give a static suffix which just works with the global prefix on the interface and the site local / ula prefix it uses

Indeed, that’s correct ula usage, but shouldn’t need nat rewriting. The global prefixes just need to be advertised by RA packets

Note that Android doesn’t support DHCPv6, just in case you have Android devices and ever have to debug IPv6 on them.
Yup indeed. That’s why it advertises both dhcp and slaac
Yeah I’m not using NAT, sorry for the confusion.
My router doesn’t support RAs for a ULA range though, so I’m running radvd on my home server.
