Extended capabilites(UnSigned) doesn't have access to system/private folder, but have screenshot tools, able to kill processes, etc.
Capabilities: PowerMgmt Location SwEvent ProtServ NetworkServices LocalServices ReadUserData WriteUserData ReadDeviceData WriteDeviceData.
Basic capabilities(Signed) doesn't have access to system/private folder & screencapture tool, not able to kill processes.
Capabilities: NetworkServices LocalServices ReadUserData WriteUserData ReadDeviceData WriteDeviceData.
The advantage of the signed version is that you can have better control over to access your device files, folders and connection settings.

Well, as far as I know, applications are signed to assure that it is safe to use those applications.

If an application is unsigned, then the OS might prompt you saying that the application is not signed, and therefore, can be a malicious application.
It warns you to use only those applications whose source you are aware of.

If an application is signed, then the OS verifies the authenticity of the application. Signature can also be used to verify the integrity of an application..

This is the need for a digital signature in any application or document or anything..

What do you exactly mean by "able to kill processes"? Which processes it can kill? Can you please elaborate?
