I thought a High Sierra or later install always converted an internal SSD to APFS. I just installed it on my MBP (coming from Sierra) and no APFS.
My internal SSD is partitioned into two volumes. Could that be why?

You didn't mention what type of MBP and what brand/model SSD.
Some 3rd party upgrades for Retina MBPs aren't recognized as SSDs for this purpose, or appear as an odd logical group that doesn't qualify. Some have weird firmware issues. The installer won't do the conversion if your SSD is outside of spec. Sometimes the install aborts in these cases and sometimes it completes.

do you know of any model off the top of your head that is affected by this?

As I recall, even SSDs from OWC had problems with HS for awhile because the firmware made the SSD look like a hard drive or RAID.
