Couverture or baking chocolate?
One is defined by law and the other is a shelf position. Which you need depends entirely on whether the chocolate has to flow.
If you read nothing else
Couverture for anything that has to flow and set. Ordinary chocolate for anything baked. Check what 'baking chocolate' means in your country before substituting, because it means two different things.
What each word means
Couverture is a legal grade: at least 31% cocoa butter in the EU, which is what lets it film thinly over a dipped item. It is a specification.
Baking chocolate is a shelf category with no fixed meaning. In North America it usually means 100% unsweetened chocolate; in the UK and Australia it usually means a sweetened dark chocolate around 50%, and some products sold under the name are compound coating rather than chocolate at all.
When you need couverture
Whenever the chocolate must flow thinly and set with a snap: dipping, enrobing, moulding, decorations, anything tempered.
The extra cocoa butter is doing structural work there, and no technique substitutes for it. This is the clearest case in the whole domain of a product constraint rather than a skill one.
When it makes no difference
In a bake, where the chocolate melts into a batter, cocoa butter content is largely irrelevant and couverture is money wasted. Ordinary dark chocolate at a sensible percentage does the same job.
In a ganache it helps slightly — a smoother, glossier emulsion — but a good eating bar is entirely adequate. The one thing to avoid in both cases is chocolate chips, whose reduced cocoa butter is a problem in any melted application.
