Who should pick the music?
It's already been picked.

If you want to pick music, you need to be the conductor of a secular ensemble or choir.
We spend a lot of time at work discussing repertoire, editions and how we are going to source the score and parts. Then we have to crow bar rehearsals into a packed working week.
On Monday, I conducted an extract of a Haydn oratorio at Prize Day. You will be fascinated to know that the orchestral parts were printed off IMSLP, my HoD sourced a continuo part for the chamber organ we hired, from I don't know where and I got the full score (Dover Edition) from Schott's Great Marlborough St. The choir parts, he did.
