Help Organizing Ranks/Duties in FC

Afternoon all, I'd like to get some advice on what you guys do in your FC's regarding rank names, structures, duties and such. I'm the leader of an FC on Bryndahir (I can't spell it an too tired to look it up). I'm looking for any advice to help run a great FC, keep it fun, social and to avoid it feeling like work.

Currently we have Commander/VP/Captain/Veteran, etc... seems ordinary, wanted to spice that up a bit, however I'm not very creative. Any suggestions?

Also, trying to keep it fun not work, but I want our FC to have weekly /monthly events. Photo night, Treasure hunting, FATE Farming, making sure the buffs are always up and running, updating company boards, company chest, decorating house, gardening and of course organizing raids. Are there titles for these people, do you just assign them? Any others that are good to add?

Just curious how others do this, any and all helpful fe4edback is greatly appreciated.

How big is your fc and does it have a theme? Your naming will chage with your theme, the quantity and complexity of ranks will change with size.
Coming from relatively medium sized fcs (30-40) my experience is generally:
Master: 1 has impunity to everything. Only person with access to the gil withdraws
Lieutenants: 3-4 restricted housing purchase/destruct access to all else.
Captains: generally the ones forming parties for the fc, access to a single chest bin that stores finished food.
Members: everyone else, deposit only access to chest can move and place housing items but not remove

Then you have special ranks, these have the rights of a member + a specific use. The members can be adjusted as needed by lieutenants.
Chef: access to crystals and bins in chest for producing raid food.
Gardener: access to plant/harvest
Decorator: access to remove items from the house
