I wish to have two volumes on a drive (not SSD); one HFS+, one APFS.
Would it be better to have these on an HFS+ partition or APFS?
APFS and HFS+ volumes on the same partition

Well, you would need a separate partition for each volume type. In other words, APFS type partitions can hold multiple volumes, but each must be a APFS volume. HFS+ type partitions can hold a single volume which must by HFS+ type.
In addition the first partition is usually a EFI type partition which contains a single volume of FAT32 type. So, you would need at least a total of three partitions on the drive.
