In Imperial, we normally collect feet and inches in separate fields, often via dropdown. In metric, what's the standard?

Collect in centimeters. It requires one input field for the user (so there's improved efficiency) and centimeters are more commonly referred to when talking about a person's height (so it's more relatable to the user). For example, Wikipedia use centimeters to refer to height as shown in the link to an AFL players bio (https://en.m.wikipedia.org/wiki/Nic_Naitanui) which refers to their height in centimeters.
On which to use - This depends on your target market. A bit of user research will reveal some pretty good indicators. For example Doctors might use a different kind of measurement than a teacher or a student etc. The answers are in user research.
Good luck
