I would like the prices, shopping cart, notepad and wishlist only for logged in users available.
How exactly do you have to set it so that it is only available to logged-in users.
You won't be able to do that with Magento out of the box.
I'm not sure which kind of restriction you want to apply but maybe you can start lookign at the marketpalce for some solutions: https://marketplace.magento.com/catalogsearch/result/?q=private%20sale#q=hide%20price&idx=m2_cloud_p...
Also you can search for private sales to see another kind of alternatives.
