Use the samplerate that the majority of your music has.
Bit depth can be left at max., i.e. 24 or 32 bit.
If you play 16 bit files the missing lower bits are treated as zeros with no adverse effect.
If letting CoreAudio resample everything to one output sample rate, need to reduce Apple Music app volume by 3dB?
For digital headroom for resampling? To avoid digital clipping before it even reached ADI-2?
Usually yes, how much depends on the resampling algorithm.
Give it a try:
• Bring down volume to -10 dB in Apple Music.
• Play some different high res tracks, preferable those that are mastered for permanent full-scale.
• Note the highest peaks in ADI-2’s Peak Meter, set to “Pre-FX” in Setup/Options/Display/Hor. Meter.
• The value you got is how far you can go up from -10 dB.
I.e., if you see -6.5 dB highest peak, you can go up to -3.5 dB volume in Apple Music.
Leaving an extra 1/2 dB doesn’t hurt, so -4 dB would be the one.
