It's personal preference for the most part. Sand tends to show debris more but is arguably better for the plants. If youu do use sand you might want to consider investing in an animal that will oxyginate the sand.
If you want to do an natural planted tank, I would refer to old fish lady's thread it's hard to find better advice.
What are your tanks dimensions?

How thick a layer do I need to put the plants in?
Rooting depends on the type of plant.
(when in doubt never plant too deep)
