You have a pretty low count of posts and comments and you've been here 2 months, best to focus on providing value and asking non-meta actually interesting stuff.
Its super easy to not do what you've described and fallen into: post something interesting each day or at least comment something insightful, empathetic, funny, or something of genuine engagement and dont worry about "quality", often just being a decent, normal, human is resonant and engaging enough
Also, you can literally always do what you mentioned (asking to expand or flesh out more slight content) in a curious, non-judgmental way and people will be crazy to go that extra mile for you or even way more miles than either of you initially bargained for. Try it, its fun. It happens constantly and in the same way almost every time for me. But please do lay off the "tOo MuCh SpAm/CoNtEnT" curator thing tho, nobody has the right to make these kinds of value judgments particularly when the Fedi is still so nascent and its almost always lurkers who finally explode
Nobody should be trying to limit the scope or define people's "quality" or "value" in that way
