Yep, it is more or less as it was expected to be, not updated date/time, error (irrelevant) on DHCP client, a few unneeded/unused configuration lines.
It is up to you which (if any) of the previous suggestions you want to implement, taking a port out of the bridge and set it for management only makes a lot of sense if the device is easily accessible, i.e. you can insert an ethernet cable into it, if it is mounted up a pole or on a roof, the “right” thing to do (from a good security practice viewpoint) would be to add a management VLAN.
Not exactly easy-peasy, but doable, check:

DO NOT use VLAN 1.
I would still temporarily take a port out of the bridge to make sure you don’t lock yourself out when configuring the VLAN, see:
