How to best manage product attributes in faceted search and collection results?

Does anyone have suggestions on how to best manage product attributes (let’s assume meta field attribute groups in Shopify) that then show in faceted search and collection results. Magento has this function called “attribute sets” that works well.

We need to:

  1. Tie attribute sets to specific collections (categories)

  2. Have a way to manage them (see which products in an attribute set are missing data and easily fill in information)?

We have 60k products and 400 collections and most collections/categories have different shopping facet needs/sets. I have searched for apps and solutions and have not been able to find anything except other people looking for the same thing. Open to all ideas…
