However, I'm having a hard time finding documentation on how these platform strings are to be formatted and what the options are in them. I don't even know what terminology to use to search for info on them. What are they called so I can go searching?  Right now, I just have arm-apple-darwin hardcoded into the port file.

That is called a "configuration triplet" or "host triplet" and usually
consists of <cpu>-<vendor>-<os>. Sometimes you also encounter a format
with four tokens <cpu>-<vendor>-<kernel>-<os>, for example *-*-linux-gnu.
