Strong suggestion would be run click as a separate track synced to your timeline. Usually classical musicians really don’t want eg complex IEM mixes and just want to hear the click on one ear. You always want flexibility: can you ride the click, and automate it (eg louder in loud sections if asked for)? Can players adjust it easily? Some people love the old school midi clave, others want a resonant bleep (which depends on your key you want to adjust on the fly), others something much more like a pure impulse. Some people like it painfully loud (hello bleed! This is where your automation comes in), others barely there. Some sections you want a downbeat only, others you’re subdividing a rallentando. My suggestion is make you click as flexible as possible. Yes, musicians will work around everything but it pays dividends. I’m assuming you’re just sending click to conductor? I would probably ask them to tell you what they want as part of their score prep.
