When using DeviceClient I can send messages using SendEvent and files using SendBlob. But I did not find a way to receive acknowledgement that messages/files have been received by Azure IoT Hub?

The only way I found to solve this is using serviceClient.GetFileNotificationReceiver(). Am I missing something or is this the only way?

Also it seems I need SharedAccessKeyName to use ServiceClient. But this is not present in e.g. tokens created by DeviceExplorer (which I use for DeviceClient). Any advice is appreciated.

For Java and C sdks there are IotHubEventCallback and IOTHUB_CLIENT_EVENT_CONFIRMATION_CALLBACK but for C# there is no such interface implemented.

So, for C#, a message will be sent successfully if DeviceClient.SendEventAsync() without throwing any exception, otherwise it fails.

Or you can utilize Event Hub-compatible endpoint to monitor the status of operations on your IoT hub, D2C message, file upload...

For ServiceClient, you need Azure IoT Hub connection string, not device connection string. You can find it in Configuration of Device Explorer:
