Not sure you have the latest chart there for EGKK. As EGKK does have CATIII ILS approaches which is not on your chart.
You would only enter either Baro or Radio dependent on what category you have chosen to fly. The one you choose can depend on many factors, but it mainly comes down to the RVR.
There are plenty of videos on youtube that cover this subject in a lot of detail, I would suggest watching some of these, an example would be ILS Categories - [Learn How To Choose The Right ILS Procedure When The Visibility Is Not Great!] - YouTube, there are many others !!
