This is probably your best bet.  I think basically everybody has a "ONT 
on a stick" in their catalog now for both XGSPON and GPON.  Then provide 
your own switch that meets your needs for local ports.

This may be annoying if you actually want to provision several services 
across multiple ports.  Obviously you can probably do it (VLANs, etc.), 
but you'll have to provision the switch separately.  I've done some 
similar things in the past where I pre-provisioned the switch with e.g. 
two ports per VLAN (reused on different switches) so I could just drop a 
service onto whatever VLAN of the UNI on the ONT that I wanted to.

Usefully, this gets you options for not just PoE PSE demarcation but 
also PoE PD demarcation which can be very handy if you want to have the 
optical to electrical hand-off somewhere that there isn't (good) power.
