24.1 Production Series / Re: IPv6 setup question(s)

Looks like OPNsense is connected to another router, not to a modem. That router establishes the PPP link and negotiates the prefix delegation with your ISP. Since it doesn't seem to support downstream prefix delegation (or isn't configured correctly), OPNsense only gets an address.
If you want OPNsense to negotiate the /56 prefix delegation with your ISP, you'll need to set the other router to bridge mode or replace it with an actual modem. If that's not possible, you'll need to configure a static LAN address on OPNsense and a static route on the other router.
"Use IPv4 connectivity" is only required if OPNsense establishes the PPP link itself. The wording is slightly misleading, the help text explains it better: "Request the IPv6 information through the IPv4 PPP connectivity link."
