Given the below Account field:

foo__c Text(255) (External ID) (Unique Case Insensitive)

If we use the following in Apex code, does a value in the foo__c field get copied over to the newly cloned record?

Account clonedAcct = originalAcct.clone(false, true, false, false);

If so, this would imply one would be unable to insert a cloned record unless the values of non-null unique fields are cleared before inserting the newly cloned Account.

Yes, values in all fields are copied over, except those you can configure not to. The only fields you can configure, however, are the Id, any read-only timestamps, and autonumber fields.
