Disabling the DHCPv6 server in the fritz box seems to do the job. Every device now gets a working IPv6 configuration using SLAAC. Is there anything special I need to add to pf.conf(5) to make IPv6 work? Currently IPv6 only works when pf(4) is disabled. Following script also contains the contents of the current pf.conf(5) file. Neither the FAQ nor the manpages contain anything special for IPv6 and I do not see the reason the following pf.conf(5) file will not behave the same for IPv6 as for IPv4. Any hints highly appreciated.
