As for metrics - we've been working precisely on that @ https://deferpanic.com . To some extent logging as well. This means (exactly as OP mentioned) - memory, gc, go-routines, request durations, db query latency, logging errors/panics, etc.
We are extremely open to suggestions/feedback.
One key point I'd like to point out though, is that OP specifically mentioned the go kit being targeted towards a company with "100–1000+ engineers". I think this is highly on point - if you have less engineers than this you probably don't have enough resources to maintain these sorts of systems yourselves and this is where we think we can help out.
