I'm not familiar with ipe. What's it like?
There are a number of woods that can produce allegic and toxic reactions if you breath the dust. So it's always a good idea to use a mask when finishing them. Even cherry can be toxic to some people.
Most of my cutting boards and chopping blocks are designed in conjunction with the person buying them, and I use woods that fit their decor.
For instance, right now I'm building both a cheese board and a set of trivets for somebody who's kitchen is in shades of gray. Woods of choice are purpleheart and cyprus.
For another project, people whose kitchen had a southwestern theme, I used osage orange and lemonwood
As a wedding present for my son, I made them a board that was maple, but with purpleheart accents.
For breadboards you can get away with flatgrain pieces, and scraps often work out. But cutting boards, chopping blocks, and counter tops should be either edge-grain or end-grain; and that requires measured amounts of the stock.
