Blocking inside a switch case

On an embedded system, running freertos, is there any reason why you would not have a blocking function inside a case of a switch statement?

For example, a thread running through a state machine and one of the states is a wait for a task notification.

Typically I've done this with if-else's but is there any advantage or disadvantage to making it a switch case?

Using cpp17 and avoiding STL.

TIA
