Drupal 8: Rendeirng node fields in another region
Easiest way to do this is create a View with a block display, and set the node ID as the contextual filter. The output of the View should be "Content" and a view mode - this view mode can be set with its own twig template in the theme. You can add a view mode at Admin &gt; Structure &gt; Display Modes &gt; View Modes, then go to whatever content type you need it for and configure the display. On the view mode, you can pick and chose what fields should display and what formatters they use.

Here is a good write up detailing it, and a YouTube video walking through view modes and what they are.

Once the View is created, you can place the block in the block admin, and set its visibility settings to only show on your content type(s) that you configured.
