If you have (international) standards to adhere to, you are out of luck most of the time since they specify the exact schemes and cryptography required to adhere to the standard. Adoption of encryption/signature schemes is slow at best unfortunately. If you do not; go wild. If you like big keys, get some 'quantum proof' public cryptography while you are at it.
