I have this interesting result though:

Here, I have one (amount correct) link-local address (address incorrect)
but two (amount incorrect) global addresses, one of which is correct.
I can ssh into the system using the correct EUI64 global address.
For comparison, here’s a bullseye system in the same LAN:
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group
default qlen 1000
link/ether 00:1d:e0:77:c1:7b brd ff:ff:ff:ff:ff:ff

inet6 fe80::21d:e0ff:fe77:c17b/64 scope link

All addresses and amounts thereof are as expected.
