Unable to find reliable dynamic selectors in Salesforce application(Products page)

Hello,

We are working on Salesforce automation where we read products from csv/excel file and add them to given customer in Salesforce Products page.
For choosing the sub products and adding the price information, we are not able to get reliable dynamic selectors.

We have tried several possibilities, which has always taken us to a dead end.

Any suggestions would be greatly appreciated.

Thanks!
