Once a transaction is initiated without Full RBF enabled you wait for the confirmation or the transaction been dropped.
For now most nodes still use opt-in RBF as default, but very soon more nodes will switch to full RBF and what that means is that you can bumb any unconfirmed tx even when you didn't opt in to RBF while creating the transaction.
because you can’t change the destination address using RBF. It can only be accomplished with the CPFP method.
You can, you can spend the input to any address you want, but paying a higher fee for it, which will most likely get it confirmed faster than the initial transaction.
