barracks

[Lazerz]

Do the armor stands, weapon racks, and cabinets actually function and do anything? Sometimes they'll put a few items of their armor on the stand but besides that, i never see them use any of the other furniture. It gets a bit frustrating watching them run half way across the fortress everytime they need to train or following orders.

They are supposed to be able to put stuff there if you set the barracks that way but there is currently a bug with it.

In most cases you want your military to equip their gear at all times anyway (to prevent having to waste time going to equip stuff before going where they are told) so it shouldn't be too impactful.
For your civilian squads (at some point you might want everyone to do some light training to be able to not die pitifully to the weakest enemies) you would probably want to put a stockpile for armors and weapons close to the barracks instead.
