When you connect OPNsense directly to the ONU, the /56 gets delegated to OPNsense and you can use it for your LANs. But if you connect the rental router to the ONU and OPNsense to the rental router, the /56 gets delegated to the rental router. It is then up to this router to delegate a subnet (e. g. a /60) to OPNsense. Whether or not it can do this is the question. More often than not, these basic ISP routers are only meant for directly connecting devices and don't support downstream prefix delegation. So if you don't have to, I wouldn't use this rental router at all.
Some ISPs don't assign a WAN address. If you made sure "Request only an IPv6 prefix" is disabled, then that's probably why you only see a link-local address on the WAN interface.
OPNsense doesn't support automatic DS-Lite configuration, but you can manually set up a 4in6 GIF tunnel.
