Those are my areas as well, e-learning, and simulations.
How does that SCORM asset work so far with AC? Have tested it before with the included example and it seemed to be the one that was the most efficient to set up for SCORM reporting (using just vanilla Unity, haven't tried it with AC yet). Assuming you're referring to this one: https://assetstore.unity.com/packages/tools/integration/scorm-api-53523
Sounds like it was worth the purchase. Did you get it on sale; or a couple years ago? Appears it's $30 now, though probably still worth it.
If the number of e-learning / simulation projects created in Unity is high, then definitely worth it.
I also have and use Playmaker at times. In general, I agree it would be great to see AC and other visual scripting tools integrate well with SCORM.
