delta between old and new 'fundraising' apps

With the Fundraising & Engagement app no longer available for license, is there any good dox that captures the differences between it and the Fundraising 'template' app that remains available from Nonprofit Cloud Solutions? What is in Microsoft Learn seems mostly tailored for the sunsetting package.

For example, Receipts is still available in the Cloud template, but it appears to be totally manual.  No automation, Receipt Batch, audit trail, etc.

For nonprofits considering the Msft NP 'stack' of Fundraising+Volunteers+Outcomes+Grants, it's hard to do a decent evaluation of this (vs., say, Salesforce Non-Profit Cloud, where the docs for each are almost current with actual feature set.)

For the bonus round, I'm interested in how non-profits are integrating their payment processor's transactions (ccard, etc) into Fundraising.
