Let me offer a slightly different take on this.
I tend to build multiple Goods buildings of the same type, based of course on what goods deposits I unlock but also on such criteria as their perceived scarcity in the Marketplace and the size of the Goods building, necessary population and the occasional plus (or minus) to Happiness. Several of those won;t be a concern for you at your stage of the game (pretty sure that all Goods Buildings require the same population and none of them affect your city Happiness, though they are different sizes).
Yes, it has happened that the Goods I produced were slow movers in the Marketplace. However, that was a rare occurrence, and a good Guild will help out by picking up trades, made in accordance with rules governing the ratios for trading (so-called "fair trade" rules). I appreciated it early on, and I try always to return the favor now.
Lastly, I would agree that, whatever Goods buildings you do decide to build, let them be of your current Age and not an earlier one unless you just have space or population left over. And excess population happens much more frequently than excess space.
