I don't know much about CF templates, but stripping some detail from your
middle fragment moves further from data and to a DSL:
(deftemplate my-template
:aws-template-format-version "2010-09-09"
:description "My description"
(param my-parameter :type :string :description "My string parameter")
(mapping my-mapping
:first-level-key-one {:second-level-key-one "Value"}
:first-level-key-two {:second-level-key-two "Another Value"})
(condition my-condition (not my-parameter))
(condition my-second-condition (= (-> my-mapping :first-level-key-one
:second-level-key-one) my-parameter))
(resource my-instance aws.ec2/instance :image-id "ami-79fd7eee")
(output my-first-output (:instance-type my-instance))
(output my-second-output my-parameter))
