I'm not saying that achievement can't be a good thing. I just think an upbringing which heavily idolises achievement could be problematic, and probably isn't worth it. And your arguments to the contrary feel epistemically circular. You're using your belief that achievement is good to evaluate whether your upbringing was good, but that belief was itself installed by the upbringing, so it can't logically function as independent confirmation

But to answer your question, yes, there are serious moral frameworks in which achievement (of the sort you mean) is neutral or even undesirable. From a Buddhist or Stoic standpoint, being attached to material achievement is as a source of suffering. For hedonists, achievement is only good insofar as it produces happiness. In care ethics, relationships matter much more than accomplishment. All of which is to say that it's not a self-evident truth that achievement is inherently good.
