Hi Don,
Thanks for reaching out. The campaign_audience_view does not have a CpcBid analogue field because campaigns do not have CPC (though they may have bid strategies that set CPC).
Regarding your second inquiry, please see my notes for each field:
"Audience segment max CPC": I'm not seeing this field in this report
"Ad group default max. CPC":: ad_group_criterion.effective_cpc_bid_micros
"Targeting Setting":: ad_group.targeting_setting.target_restrictions
