Renovation of electrical wiring in a terraced house built in 1961, how to plan the wiring?

By low voltage I understand everything <230V. That means Ethernet cables and satellite cables.

Have you made any progress yet? I would like to proceed in a similar way. Our advantage is that it concerns the apartment on the ground floor and a large part of the cables can then be routed through the basement. Conversation with the electrician is still pending.
