Upright cabinet organizer with several slots, get an expandable with adjustable slots if possible.
Put the things you reach for most often in the easiest spots, and reserve high, low or deep storage for occasional-use supplies. Group like items together so you can see what is running low before buying more.
My final check is practical: can you find what you need quickly, put it back just as easily, and see when the space is getting full? If not, simplify the categories or move the storage closer to where you use it. An organizing system should make life easier, not become another chore.
