The ferrite bead will do nothing. The others will not protect 5V digital circuits from a power supply overvoltage. They don't have a sharp enough "knee". The voltage will be well above 5V before they do much.
A "crowbar" could be a solution, but I suggest one of the following:
1. A low dropout voltage regulator
2. An emitter follower with the base driven from a higher voltage via a properly selected base series resistor (so the base current is guaranteed to be less that the current needed by the circuit).
