What is the best alignment of the main container in a dashboard if just a little content is displayed?

Let's say the dashboard has a classic structure - header, footer, sidebar and the main container on the right side. This container usually has some text and a table (with a small with) or one-two graphics. What is the best approach for this:

  • left aligned elements;
  • right aligned elements;
  • justified content (full-width tables)?

In my opinion, left-aligned content is the best solution because with centered content none of the familiar patterns (F-pattern, Z-pattern) can be applied. What do you think?
