Have you considered syncthing? There’s shiny new and super cool Sushi Train (or Sync Train by other name) app for iOS (I wish the author would make it a paid app, so much I like it!): https://github.com/pixelspark/sushitrain https://github.com/pixelspark/sushitrain Not affiliated, but a very happy user.
