Erm...this is getting waaaaaay off topic...but, if you specify a pitch without 
any other context, equal temperament from A=440 really is the standard. All of 
your examples have context.

There's no C in an A Major triad. There's a C# in an A Major triad. The C in an 
a minor triad would need to be raised by a few cents. The C in an Ab Major 
triad would be the one needing to be lowered by several cents...in isolation, 
since, in practice, chord progressions influence the required pitches of 
surrounding chords. Think, for example, pedal tones...in some cases, the pedal 
needs to be kept constant (which will require the other notes to shift), and in 
others the pedal needs to be the one to change pitch, and still others both 
need to adjust...and all of this needs to take into consideration the quirks of 
the particular instrument, which will already deviate from equal temperament by 
a fair amount...

...assuming the rest of the ensemble can actually play in tune, which is, 
sadly, an all-too-rare occurrence....

As you might guess from my domain name, I'm a professional trumpeter....
