I usually use https://github.com/cockroachdb/errors for reasons that you can read in their documentation. It is well thought out and is no more complicated than it needs to be. It is a drop in replacement for the standard errors package and they have built this from experience, which is usually a good thing. It is usually best to stick to interfaces. With concrete errors, you will be doomed to deal with them forever.
