To preselect the first child product on a Magento 2 configurable product page:

1. Ensure all child products have stock and attributes are correctly set.
2. Magento usually selects the first option automatically, but if not, use JavaScript to trigger the first available swatch on page load.
3. Add a custom script in your theme’s JS folder and include it in requirejs-config.js.
4. Deploy changes using Magento CLI commands.

This ensures the first available size and color are auto-selected on page load.
