So if anybody facing the same Problem with fritzbox PD (opnsense behind fritzbox), my solution is ULA Adresses. Then you just need to set a static Route in your Fritzbox to the ULA network you definded in OPNsense with the ipv6 gateway of your opnsense wan.
But if there is a solution for a stable PD Delegation from the Fritzbox i would be interested as well (just mentioning that the PD of my ISP is always the same, so this is not the problem here).
