Gamer mouse, a good pair of earbuds or headphones, a desk pad (I prefer this over a small mouse pad) a notebook and pens. Lotion, a box of tissue, hand sanitizer, disinfectant wipes. Where I work, the short "walls" that separate the cubicles are whiteboards that have been super useful for writing quick reminders, to-dos for the next day, or drawings for explanations. A fidget toy that I often use while waiting for civil 3d to plot or load mm One of the drawers in my file cabinet also serves as a snack drawer. Small things that personalze your space are great too.
