I am not sure you can find someone who knows (almost) everything about
disks and partitions even on OpenBSD area. There are so many "standards"
and "methods" that the utilities got their names in time:
fdisk - %#@& disk
dd - destroy disk
disklabel - diskbabel
But maybe I am mistaken.

Um, well..
What I was going to say is, for some reason the default disklabel
doesn't pick up your partitions (it should also show the EFI, but
doesn't).
As a quick-and-dirty fix you cold try and change the partition ID to
something that's picked up by the d

That is incorrect.

You probably wrote a BSD disklabel to the disk before creating the ExFAT
partition.
If there is no on-disk disklabel, the kernel will create one in me
I have two disks, one an MBR partitioned 1TB external SSD, and the other a
GPT partitioned 5TB external HDD. Both have a single ExFAT partition on
them and both have the same contents. Both show up as sd1 under "sysctl
hw.disknames" (when plugged in one at a time, that is). I am able to mount
