Unfortunately you have to choose between form and function. Every player gets 3 boosted goods, one from each tier.Part of the game for me is the aesthetic appeal of the city; hence my desire to have a variety of manufactories and not focus on just a production mentality for only 1 or 2 goods.
The boost system is designed to promote trading and gives incentive to join a fellowship.
At max level your boosted goods make 8 times as much as non-boosted.
So if you are boosted in marble, a marble building would make 32,000 marble a day, and a plank would make 4,000.
With the general suggestion being to make around 6 Tier 1 buildings that means that instead of 192,000 you would make 24,000.
You might like the look of having some of each, but running 9 different types of factories means you will always struggle.
