No. It’s not random. SLAAC uses EUI-64 by default, it generate fixed /64 suffix from MAC. And with suffix match of nftables you can still do device specific income firewall rules. For random privacy address, it’s only used for outcome so just block all other income of IPv6 addresses except EUI-64 is enough.

I don’t want each client to have a globally unique address as that just allows insane tracking.
Just for this issue, SLAAC has a privacy extension to generate temporary random IPv6 address for outcome traffic. It’s untrackable as well, but in different way to NAT (one device has many addresses instead of many devices have one address).
It “converts” from and to Ethernet frames, of course. There is not actual L2 difference between PON network and normal fiber ethernet network. In simplified description, it just replace active switch with passive optical splitter.
Yes. Like fiber ethernet, differnet speed need different ONT. But noteworthy, there are some different standards for the same speed level, they are incompatible. For example, EPON and GPON, they are both for 1GbE but incompatible.
