There are different types of execution to highlight the various severities of the sin for which the sinner is being executed for.
As the Rambam writes (הלכות סנהדרין פרק יד):
"Stoning is more severe than burning, burning is more severe than beheading, beheading is more sever than strangulation."
Similarly there are various types of "heavenly killing", e.g. כרת, מיתה בידי שמים, ערירי depending on the severity of the crime.
There are also different types of Korbanot, depending on the sin.
