Finally got the complete process working, using standard Acumatica code and Automation steps. This was particularly painful for me, being new to Acumatica, and I've had to take many breaks from it as I learned other parts of the system and tools. For those that want to avoid the countless hours of trial and error that I endured, here is the relevant code for your customization in 2018R1. (I understand some things may have to be rewritten for R2, so be mindful of your version if you are having trouble making it work.)
Before you dive in, please note that I left the original answer because it was part of my learning curve and may help you relate from where I started (which might be where you are) to where I ended up with it working as desired.

My Automation Steps. This is in XML generated from the Automation Definitions screen, but you would be best served to learn to read this format and duplicate the appropriate steps in your Automation Steps screen. In my case, I leverage a non-database field for approved to help trigger the advancement of approvals (EPApprovalAutomation) but my statuses go: On Hold -> Pending Approval -> [Approved|Rejected] where I don't actually need to store "approved" in the database.

The other parts of the code, including the setup screens are easy enough to create following Brendan's post mentioned in the original post. These code samples should guide you through all the parts that I struggled with through a lot of trial and error and trying to follow breadcrumbs through the code (with a lot of the trails ending at just metadata instead of full-blown code that isn't actually in my CodeRepository).
With the answers right in front of me, this all looks pretty simple. But now knowing how the system processes approvals at a code level made it very challenging for me to find the way.
Fundamentally, understand that EPApprovalAutomation is the standard approval hook. It manages the EPApproval records which are the actual approvals. You will need to setup an Approval Map for it to understand the approval tree to follow, but again, Brendan did a great job explaining those setups in his post.
You tell EPApprovalAutomation what the document/record is that you want to approve and give it the relevant field names it will need for managing approval. I set the field for approved or rejected in the automation steps, and EPApprovalAutomation notices the field set to true to process the approval step. Note that it appears to only really manage the EPApproval records based on the inputs. It will lookup the proper approval map and either leave the approval completed or lookup the next step to get that started.
The Automation Steps must be written in a way to manipulate fields like status when the right conditions are met. In my case, approval happens when the approved flag is still set after the rest of the code runs in response to the Approve button. Since I don't save to the database, I can just look for when the field in my DAC is still set to true and then toggle my status to Approved. On Reject, just go ahead and set rejected to trigger rejecting the approval and then set the status right to Rejected on my document.
I am still fairly new to Acumatica, so there may be better ways to do some of this. If you happen to be more experienced and have some insights that may help us all improve our skills, please comment.
