Writing this to provide a fresh, new player's experience, as I understand that sometimes with time/experience in a game, you can easily overlook which information is taken for granted.
What I wanted to focus on in this write up is the inventory UI - particularly the quantity limits. There's a couple of discrepencies in the design that aren't inuitive.
The bank inventory slots for small items are not shown.
I was originally placing items into the bank in stacks of 10, each getting their own slot. There is no indication in the bank UI that small items have a higher stack limit, and I discovered this when I shift-clicked a stack (10) of strawberries from my inventory, and all 6 of my stacks neatly stacked into 1 slot.
Additionally, there is no way for me to see what a slot's maximum stack size is-- nor is there a way for me to predict it. The maximum a big cargo item stacks is 10 in my cart, and 100 in my bank. So if the stack for strawberries is 50 in my cart, is it 500 in my bank? I dont know!
The inventory slot for the large cargo item in your personal inventory doesn't show a limit.
Your bank shows 0/100 which is good! Very clear. The cart shows a limit of 0/10.
