I think this is a valuable subject, but perhaps many people don't see it here because this question was posed in a support forum.
I think it may strongly depend on the set-up and on the acoustics in the church. Based on how St. Anne's sounds in my living room (I've no experience using virtual instruments in a church setting, so don't take me too serious
), I would suggest the following:
* During preludes, you can register almost anything, but during singing, some of the more powerful stops will be required to support the congregation
* I think a solid pedal line is mandatory, the Diapason 16' + a 8' in the pedal is a minimum in any choral registration. Consider addition of the Pedal Fiftheenth stop. Coupling the Swell containing the Bourdon 16 gives an even more solid foundation.
* Sad choral (e.g. passion hymn): CF (melody) on Great, using either the Large Diapason or the other 8' stops on the Great. Flute 4' may be added for a bit more brightness. Accompaniment on Swell (box open) with Geigen Principal and Rohr Flute, and Bourdon 16 for some "heaviness"
* Soft choral (e.g. prayer hymn): CF (melody) on Great, using either the Large Diapason or the other 8' stops on the Great. Flute 4' may be added for a bit more brightness. Accompaniment on Swell with Rohr Flute + Voix Celestes and possibly Geigen Principal. I would not use the Gamba, I think it is too bright with an open swell box while the Swell might be too weak with box closed. Couple Swell to Great.
* I suspect that CF on Swell is feasible only when using the Swell Trumpet. The other Swell stops may be added for colouring. Addition of the Contra Fagotto gives a robust sound. Accompaniment on Great with Small Diapason and possibly Flute 4'.
* Solid Choral (all fingers on Great): again use either the Large Diapason or combine the other 8' stops on the Great. Couple some Swell stops for colouring. Swell box may be used. Add Principal 4 for more brightness
* Interesting additional gradations in brightness may be obtained as follows: Start with Large Diapason and Principal 4. Draw Mixture on Swell. Then, first draw Swell Suboctave to Great, then Swell to Great, then Swell Octave to Great couplers. You may add the Swell Piccolo at any stage. The crescendo may be continued by adding the Great Mixture and/or Fifteenth, and by adding reeds. Do not forget to add the Trombone on the Pedal for balance, as well as pedal couplers.
