There are multiple requests. Please split it into separate issues.
In my opinion opus should be the default choice.

Sorry I am not an Android dev, I just know about the amazing high quality of opus.

Feature description
Right now there is file Extensions (following codec, not indicating container): (o) m4a ( ) mp3 ( ) ogg (Opus)
Problem: 1) container mp4 with extension m4a can contain 2 codecs: AAC (loose) or ALAC (looseless). ALAC is considered better. Which one is used? 2) container ogg is very popular and can contain Vorbis, Dirac, Opus and other codecs. How can someone afterwards identify which one is used in this ogg? Specially for this .opus extension has been officially registered (probably in 2018), so the file with opus codec has .opus extension as this is modern and all major operating systems recognize it.
https://wiki.xiph.org/MIME_Types_and_File_Extensions#.opus_-_audio.2Fogg https://en.m.wikipedia.org/wiki/Opus_(audio_format)#cite_note-MIME-and-FileExt-1 So the codec is Opus, and the container format is Ogg, but the "official" file extension is .opus. 3 different things.

Offered change: ( ) m4a (mp4, acc or alac) 128 ( ) mp3 128 (o) opus (ogg, opus) 128
Now default choice is m4a. If acc used instead of alac in it, opus could be made as default choice, as it generally performs better than order aac codec. P.S. Also indicate bitrate (kbps) used for each.
Why do you want this feature?
Make it more clear and standard compliant.
