There are lots of possibilities! You could try a chandelier, for example, if you want a very glamorous look. If you don't really have room for a chandelier, try a ceiling flush or semi-flush mount. Wall sconces can add another pop of light. LED tape light could be great if you have, say, rows of shoes in a display and want to illuminate them like you might see in a store. You have some great options here. Let me know if you have any questions.

Depends on size. If it's pretty compact, a nice flushmount is likely to be plenty. If it's really large, like a room, then you can do all kinds of combinations.
