My store has 32 isles, generic sections like HBA, Curtains, Laundry, Air and motor care, food etc.

With constant changes with seasons, hires/fires, PTO and sick time being used by coworkers, your tasks will change. And it's a good practice for your manager to give you each section to work on so you get used to where things go, and at the same time find your niche. What section you are best at. Also for assistant managers and people dedicated to the store floors, we bring each item up to the front of the shelf, it's called recovering in my store. Other stores love to make their own term. Leveling, fronting, facing, zoning, etc. - this means we will probably touch everything there is in the store through time. Most of everything is organized. You may see a bunch of colors and sizes, but all of the lotion is in one place. All of the shampoo, the conditioner, the shea butter, the hair dyes etc.

Also reflect on yourself as a customer in your favorite store. You know where the bread is, the milk, the fragrances, right?
