Not sure this will be what you're looking for (ie. ripe, natural tasting, slightly sweet peach), but I like a combo of TFA Juicy Peach + TFA Peach when a recipe calls for Peach. Together they provide the taste that I'm looking for.
Some people who use TFA flavorings also do the same combo type of thing when a recipe calls for Blueberry or Strawberry. They use TFA Blueberry Wild + TFA Blueberry Extra. A Strawberry combo many use is TFA Strawberry + TFA Strawberry Ripe. You just work out the % for each one that suits your tastes.
You'll notice in quite a few recipes, too, that often there is also more than 1 brand of a particular flavoring in the recipe. It may have CAP Sweet Strawberry + TFA Strawberry Ripe in it. Both flavorings bring something unique to the Strawberry taste in the recipe.
