How about specific storage? IE Weapon stands for weapons, armor displays for your armor, refrigerators for certain ingredients, pantries/larders for everything else.

How about "inspiration" buffs? Look at a fish tank to inspire you to catch more fish. +% of catching HQ fish. Or training on dummies/archery targets to get "Battle Ready" which increases the main battle stat by like 1-5? Train using the archery target as a BRD to get +2 DEX for a few hours. Attack the training dummy as a DRG and get +3 STR. Longer you train, the bigger the bonus, nothing too much, but as an added bonus for spending the money and time to get a FC HQ.
