Can auto answer be enabled at the queue level for calls? We are finding it will only work if auto answer is set at the user level.

For any Digitial channel, including callbacks, messaging, email etc you can set it at the queue level.

For voice it is only at the agent level currently.

There is an open idea: https://genesyscloud.ideas.aha.io/ideas/INB-I-414 that is currently in development to enable this for voice.
