I'm creating small encrypted disk images (under 10 GB) to be used to secure data and transfer between systems running High Sierra (for now) and Mojave. Are there any technical reasons to prefer HFS+ (Mac OS Extended, Journaled) over APFS for these images. The images will be created as .sparsebundle files if it matters.

HFS+ has more third party data recovery options and is further backward compatible so those are two main technical reasons to potentially prefer HFS+ over APFS. If you’re storing the data on a spinning disk, that might be a technical advantage or might not. You’ll have to test that on your kit as benchmarks vary widely there.
- https://en.wikipedia.org/wiki/Apple_File_System
You give up the metadata protection checksums, crash protection of copy on write and encryption advances of APFS as well as the redesign of the filesystem to take advantage of flash/ssd. You also lose snapshots, clone copy and don’t receive the more flexible space allocation features of APFS.
Speed chould be a wash on flash / ssd for your use case, but I would still benchmark your sparse images on both file systems. HFS+ might be far better tuned for a HDD still ( or possible for evermore) as APFS sacrifices HDD performance for flash and ssd performance today as implemented.
Now, within the sparse disk image, I can’t imagine you will be able to measure any performance difference between HFS+ and APFS since that filesystem is fully synthetic and depends only on the underlying writes for performance. The other technical details remain relevant for whatever embedded FS you chose inside the images.
I do not understand this answer. Q asks for small encrypted images. Transferred between .13 + .14. I read this A as primarily about FSs on real disks?

These general considerations shouldn’t matter for sparse images. We don’t need to know if the Macs are SSD or HDD and it likely won’t matter if the transfer is either. I read this as what filesystem should OP choose for the device doing the transfer. Can I make things better @LangLangC or just wait for OP to confirm I have it correct or wrong?

Nice details. Wouldn’t the sparse bundle cover the sorting, though. The OP gets to choose a FS on the transfer device and a FS for the sparse image. Perhaps this it the point @langLangC is making. I didn’t go into that in my answer.
