Build the content model around the buying question
Start with a representative product family and the fields buyers use to distinguish variants. A model may need a stable product reference, dimensions, material, application and approved technical documents. Decide which fields belong to the family and which change for each variant. Agree the units and terminology with the product owner. That structure should support the catalogue's navigation and enquiry journey, while keeping the published information tied to the person or system responsible for approving it.
