How should I organise products with many configurable options?

For products with many configurable options, separate the customer-facing choices from the underlying technical attributes. Keep the options shoppers actually need to select simple, and store additional specifications in structured fields such as metafields. If configurations become too complex for one product page, consider product families, bundles or a guided selling experience. The catalogue structure should make comparison and filtering easy without forcing shoppers to understand the complexity of your internal product model.
