I'm not sure how this applies in softwoods (like the hemlock & fir type stuff usually used in construction), but it is not really so obvious that slow growth (tight rings) is better than fast growth (wide rings) in hardwoods. The fast growth wood is usually much less likely to shatter or split under strain -- which for some purposes (anything delicate, or with staked construction such as Windsor chairs, basically stuff which needs to bend some under use) is preferable.
I'd need to break out my [Hoadley](https://www.tauntonstore.com/understanding-wood-2nd-edition-...) to confirm, but my belief is that you are trading modulus of elasticity for modulus of rupture.
