You already have my suggestion for a standard overview that puts each section in perspective across the historic branches of Christianity: An improvement to the Lexham Survey of Theology
A second suggestion would provide the context of the topic across a variety of denominations. Before the Recommended Resources section, provide a "Topic in Confessional Documents" section that gives the reference for the topic in creeds, confessions of faith, catechisms, ... and other authoritative summary doctrinal statements. This would require:
- a review of such documents and adding to the Logos library missing documents
- milestones for such documents at the paragraph/article ... level depending upon the structure of the document
- mapping similar to that being used to align the systematic theology texts.
A quick look at the work of Jaroslav Pelikan implies about 250 such documents is adequate coverage.
