Would you name your child the full version of a name or the short version?

Examples:
Samuel/Samantha or Sam
Tobias or Toby
Matthew or Matt
Maxwell or Max
Danielle or Dani
Kassandra or Kassey
Jennifer or Jenny
Alexandra/Alexander or Alex
Aurora or Rory
Jessica or Jess
Etc.
Would you name your child the full or short version and why?
Update: @Maragret Bethlims
Well I'm a girl and my name is just Rory so I like that better than Aurora but I think for names like Danielle, Samuel they sound better as full names because then you can shorten them to Dani and Sam for nicknames.
