What’s the best option you’ve found for streaming music via Webdav:// or sftp:// which works cross platform including touch screen devices?
Rhythmbox using an sftp mount (Fairly automatic from Caja in Mint 19.1,)
VLC half looks like it wants to, but more has an option for a UDP stream. I’ve not tested this yet. Thing is that it doesn’t have a column browser like Rhythmbox or Itunes.
