Hi fcoerezza,

Thanks for your patience.

1. You can use Product additional information table widget and choose which categories should be displayed https://prnt.sc/N-Lbm7rKJox6

2. There are 3 default tabs of WooCommerce:

+ The Additional Information Tab: Shows when the Attributes are added under a Product. If the Attributes are not added then the Additional Information tab doesn’t show.

+ Description Tab: This is the main description on the product page. Please enter the product and make sure you have added the content.

+ Reviews: Used to show customers’s reviews.

If you want to add additional tabs for specific product, you can add Tab via Product Setting https://prnt.sc/exIlSVXRC9_d

You can use Product tabs widget to display Description and Product attributes (Additional Information). Disable Reviews option. https://prnt.sc/5-S-SyfgA9FO

If you want to display custom attributes, which are separate Product > Attributes, you can create custom table via HTML Block > select via Custom Tab in Product Settings.

3. Navigate to Theme Settings > Shop > Single Product > Tabs. In the Additional tabs, you can remove Table title, Content to disable these https://prnt.sc/aiddjA_pEWmR
