- Its the Pi that will be the media-"center" / streaming-"client" in this setup ?

9/10 will recommend that you install Kodi in one way or another. Kodi has support for the most common filesharing protocols and the new version 18 should work well even with Windows 10 fileshares.
10/10 will recommend cabled network if you have that option.
