One additional thing I like in structured logs is having some form of context level information be included eith your logs, so that you already know things like tenant id, user id, request id, and basic parameters of the request without having to rewrite all that everytime you get an exception.
Unrelated: I live in the Pacific north west and I clicked on this expecting to find a list like "don't log old growth for timber, don't log the entire area", fun how your brain can associate a word with a concept and ignore the more context-relevant meaning.
