It depends on what your goal is.
If you just want to level, do leves.
If you want to get stuff you can sell, then check your server market board for what is selling well. The low level logs and cotton can be bought from vendors, so they won't sell well, but high level logs are always in demand. Seeds will probably sell well since they are new. Everything else is used in some crafting recipe somewhere but it really depends on people are making. When you get to higher levels, go after Rolanberries.
