Certain job specific frequencies often go unused

[Kamades]

Civvie channel is for botany to coordinate shipping with the QM, food stocks to chef, and citrus to bartender. I think the HoP has access too? At least on RP, it gets a decent amount of comms

Medical gets used a decent amount, esp if you're coordinating with a good medbay team

Command is, on RP at least, great for coordinating with other departments, setting things up, and occasionally doing Fun Intrigue Shit by "forgetting" the HoS is on there
