Answer 1

You can:

• Set default signature for everyone via Gmail API: https://developers.google.com/gmail/api/guides/ali...
  
• Set footer for all outgoing messages: https://support.google.com/a/answer/2364576
  
• Use Apps to set a signature for everyone, or individual departments: https://workspace.google.com/marketplace/app/email...
  

But, for all this, you must have a paid Google Workspace.
