I prefer the sound & length of Odessa with your other two, but I agree it’s perhaps insensitive and overly loaded to use right now.
Maybe Odette then or Octavia? Or one of the other O names above? You could repeat the “An” sound throughout all three and go, Osanna.
Similar names that could round out the set include Cressida, Delilah, Theodora, Lucinda, Jemima, Cosima, Felicity, Calista, Florence, Arabella, Hermione.
