If you use something like Navidrome to host your own streaming service you can set up automatic transcoding and enable it on your phones streaming client (I use Symfonium). This way I can always access my whole library at any point with it not using too much of my mobile data. But my flac collection is quite big and even if transcoded completely I could not fit all of it on my phones internal storage.
