Verifying multiple values in a single JSON response

I'm new to SoapUI NG Pro and am trying to ramp up quickly to help on a current project. I see this as a common scenario and have googled and searched this forum but haven't found a good general purpose solution that I can reuse for my test cases. I did find this blog but it's 3 years old and seems overly complicated to do something this common. I'm assuming that I'm missing something simple with current functionality and am looking for a best practice to implement going forward.

See the attached file for a sample JSON response. I send a request and get back a response like this with multiple "things", in this case products. How would I validate all X products in a single pass?

I have tried the verify content assert at a high level and that works but if one property on one product is off, the whole thing fails and I have to look through a large respose to figure out exactly what is different. I would prefer to put content verification at a more granular level but that becomes tedious if I'm expecting a large number of things to check. In the simple attached example, there are 8 products each with 5 properties to check so that's 40 validations that I would have to manually create. Is there a way to do multi-select and bulk create asserts like this? I didn't see anything.

The other route I am exploring is data source looping but I'm not sure how to validate all 40 properties in a single pass using looping. I don't want to resend the request each time when it's not necessary.

Another route would be scripting. It seems that it would involve parsing a large section of the datasource (maybe Excel?) and then looping through the JSON response and comparing. That seems overly involved but I'm open to that if that's what is easiest/best in this case.

Any suggestions, pointers to articles, etc. would be much appreciated.
