Reasonable staging-site solution

Being relatively new to the WordPress world, my expectation of staging workflows has been shaped in other contexts to be something like: checking in code to a branch in GitHub or similar and having automated tools then propagate the update to a staging server for review, then merging the accepted stage branch to the master branch in Git and having automated tools propagate the update to production servers. In the WP world, where so much of a site’s content and function lives in a database rather than a code repository, this model doesn’t apply. And it gets more complicated when it’s an e-commerce site using Woocommerce, and business and customer data is commingled in that same database with site content, layout and functionality. So I’ve definitely struggled to recreate a flow in the WP context that comes close to aligning with my expectations and comfort level from other contexts. Although there are potential gotchas and more hoops to jump through than I wish, this plugin is the closest thing I’ve found to providing a reasonable staging solution in the WP world.
