For typical Zk use-cases, Consistency is non-negotiable; so CP. That said, typically A is not black/white even if you are working with a CP system, you can get a degree of availability. For prod use-cases, instead of a 3 node cluster, try to setup a 5 node cluster and write some simple scripts/automation to heal the cluster on failures (read the admin docs) - https://zookeeper.apache.org/doc/r3.4.10/zookeeperAdmin.html#sc_supervision You can scale reads via observer nodes but you cannot (and should not) accept writes without a quorum.
