Why to select different sub carrier spacings (pros and cons)?

Hello Experts.

For 5G NR, there are different sub carrier spacings available.

Why to select one vs another, and the associated pros and cons?

Source: Numerology - Subcarrier Spacing

Generally, higher SCS will lead to lower latency, because the higher you subcarrier in the frequency domain, the shorter he is in time domain. So if your goal is to achieve low latency, you should transmit (and recieve) at higher SCS.
Obviously, your BW depends on the SCS. So if your device can’t support high BW, you wiil select lower SCS.
