For serial communication, is the baud rate of 9600 sufficient for all projects. Or will I have to change it for some projects?

It really depends upon what you are doing, and what processor you are using.
If all you are doing is monitoring an event that occurs a couple of times a second, or less frequently, then 9600 is fine. But if you are monitoring something that happens hundreds or even thousands of times a second (in which case you probably are using the Serial Plotter instead of the Serial Monitor) then it might be too slow.
Plus some processors like the ESP32 generally use a much higher baud rate.
Just match it to whatever your code requires.
