If you have the same master*, there is no audible difference between 16 bit and 24 bit. That is to say, it doesn't matter. In fact, a lot of "24 bit" files were ripped from a 16 bit source anyway, since that is the standard for CD-quality audio.
There is a lot of misinformation about this online, since people just think "bigger number better". But bit depth only affects dynamic range and noise floor, with 16 bit giving you 96dB of dynamic range and a noise floor that will be inaudible at normal listening levels (you would have to turn up the volume to extreme, ear damaging levels to hear the noise floor).
*to be clear, streaming services pretty much always have the same master for any song, since the songs are distributed by third party companies to all platforms.
