2 things:

1) see above, can you add dot1q encaps to your cisco config?

2) you're running the switch in standalone mode. This wont be discovered by the FGT like this - please follow

can you also add Switchport trunk encaps dot1q to your cisco trunk config? some switches dont default to .1q

You have to create VLAN 21 if you plan to use it for access in FSW from GUI:

Switch> VLAN [+ Add VLAN]

make VLAN 21 as native in one of the port, connect a device and check if the MAC address is learned in the FSW and after that check if it's spanned in the Cisco switch also.

# diagnose switch mac-address list | grep -i mac

is the license impact on the operation since i see the license is not active while it is added on the portal and register
