Thanks for your response, @ryanr14! Frankly, I don’t have a clue why it works much better than the other proposed solutions :), but it can be used to hide price and related products. Interestingly, I still cannot hide meta info, including category list. Please head to https://dudaskrisztina.hu/termek/5-alkalmas-lomi-lomi-masszazscsomag/ and look for the category info, circled in the screenshot at https://prntscr.com/pwyum8.

The product page is built along the following hooks:

		 * @hooked woocommerce_template_single_excerpt - 20
		 * @hooked woocommerce_template_single_add_to_cart - 30
		 * @hooked woocommerce_template_single_meta - 40
		 * @hooked woocommerce_template_single_sharing - 50

Here I can remove the one with prio 30, but cannot remove the one with prio 40. According to WooCommerce doc, woocommerce_template_single_meta calls single-product/meta.php, which contains the PHP code to display categories. I would expect the remove_action to remove this hook and, in turn, this template to not be called ever.

BR.
