The HH5A internal LAN has no internet, however.

So basically the Home Hub 5 can act as a VDSL modem and handle the PPP connection while also acting as WiFi AP, all while using a different router for the actual routing? That's pretty neat if so.
Have you done any testing to see if heavy WiFi use slows the PPP connection down?
I tried to get the HH5A to share the pppoe through its red WAN port with a 2nd router, but at the cost of not being able to use the pppoe itself.
I haven't tried any speed tests on the wifi, but it shows up on the scan as present.
Answering my own question, the WiFi on the HH5 is massively bottlenecked by the CPU on LEDE (it can't get close to normal 802.11ac speeds) so its definitely going to slow down PPPoE if its used heavily.
I'm probably going to play around with this, although personally I will be trying as you said to just bridge everything over to my router so that can handle the PPPoE load. Mostly I'm just curious to see how the VDSL modem compares to the HG612 and getting some bonus Switch ports would be useful.
Has anyone here had luck to setup a 2nd router to manage everything else, and keep hh5 to just manage pppoe / modem only ?
Doing PPPoE on one device and bridging that traffic to another is a massive hack, I wouldn't recommend it. Far better to do PPPoE on the router and leave this as a plain bridge.
I've found it rock-solid stable when using it on VDSL2 in that mode, except on my G.INP line where it randomly resyncs for no obvious reason so I used something else on that one.
