How to get products from wishlist in Model using customer id?

Answer 1

You code was correct and nothing to do with this.

See

https://github.com/magento/magento2/blob/2.3-develop/app/code/Magento/Wishlist/Model/ResourceModel/Item/Collection.php#L243

On _afterLoad() resource collection of wishlist items, the products collection was already loaded to the wishlist items

https://github.com/magento/magento2/blob/2.3-develop/app/code/Magento/Wishlist/Model/ResourceModel/Item/Collection.php#L292-L321

So to call the product each item, from foreach loop you could do

$item->getProduct()

Which attributes will be available for this product?

See https://github.com/magento/magento2/blob/2.3-develop/app/code/Magento/Wishlist/Model/ResourceModel/Item/Collection.php#L295
