Usually, when people type in "coffee table," the safest bet for that search term is some sort of e-commerce results like a list of products from Amazon, IKEA, and other high-authority, big name, branded sites.
You're not really missing much of anything because if you were to target the keyword "coffee table" and you have this no-name, no-brand website that you just started yesterday, the chances of your ranking for that keyword are almost zero.
No big loss there!
So focus more on actual searches for information like "what is a coffee table?" or "how can I clean a coffee table?" or "how can I repair a coffee table?"
That kind of thing.
Your concern of people looking for information on "what is a coffee table?" entering the phrase "coffee table" happens fairly rarely.
If people really wanted to look for specific information like "what is a coffee table?" they would enter that.
Google is showing the results from big branded websites that way because their results match roughly customer expectations.
Let's put it this way.
Google will not continue to list that type of results if it turns out that the vast majority of people that type in "coffee table" actually intend to search for "what is a coffee table?"
It would not be in Google's commercial interest to keep sending the kind of results that you have described.
So, according to their algorithmic calculations, whatever they're doing now is the best fit for the otherwise amorphous constellation of needs of people typing in the keyword "coffee table" into Google.
