How to directly access translated variables by language
Take a look at the Craft docs page for &quot;Globals&quot; under Querying Globals.
You can pass a site ID number to an element query to get globals from another site/language. For example, if your French site id number is 2, you could do this:
{% set siteOwnerInfoFrench = craft.globalSets()
  .handle('siteOwnerInfo')
  .siteId(2).one() %}

{{ siteOwnerInfoFrench.siteOwner }}
