What are your expectations (beside delicious and healthy)? There are several distinct types.
yeast breads - Italy, Portugal, New England make regular wheat bread with the addition of cornmeal. There was just a thread about Anadama bread (a NE version with molasses).
northern cornbread - a quick bread (baking powder) with roughly equal parts flour and cornmeal. May be sweetened, and may have lots of add ins (corn kernels, peppers, cheese, etc). If you haven't grown up with the southern style, you may find this most delicious. Think corn muffins.
southern cornbread - those who claim this is the only kind, focus on the lack of sugar, though I think the use of 100% cornmeal (no wheat flour) is more distinctive. If you did not grow up with it, it might seem dry and boring. Use of buttermilk, bacon fat, and a hot skillet that produces a crisp crust, help with flavor and texture.
spoon bread - an egg rich dish, almost more of a souffle than a bread. May be a good option if you want to serve it as a Thanksgiving side.
jonnycake etc - various dense corn cakes, made without a leavening agent. Often more of a baked corn mush. This is the most traditional kind.
These breads don't vary that much in 'healthy-ness'. The bulk of the bread is cornmeal and flour. Stone ground cornmeal will have more corn bran and germ. But if the supply is old it can be rancid. Ones without much fat can be boring and flavorless. And depending on your tastes, ones without sugar may not be delicious.
My absolute favorite, if you like a sweeter (rather than bacony) cornbread. It's in the oven in about 3 minutes.
