Got it solved.
When using the flow editor, adding a "set variable" step automatically wraps the action in an "apply to each" step, using body('Parse JSON')?['body']?['value'] as the output to use. Using the expression editor to change this to body('Parse JSON')?['value'] solves this problem. Example screen shots below.
Requiring the author to make this change feels like a bug, as it defeats the purpose of using a no-code tool.
Looking at some other related posts, it may be a result of the JSON having an array named "value" within the "body." If so...it's definitely a bug.
