link local addresses, as the name suggests, are only valid within a layer2 broadcast domain.
You say "From br_lan I can not reach br_wan via GUA if both bridges are configured with the GUA address" - you should assign different GUA addresses to each otherwise routing will not work. Typically you would be assigned or use an autoconfigured (SLAAC) or DHCP address (/64) on the WAN and use routed static or DHCP delegated prefix addresses for any other interfaces.
