The point of view of a story determines who is telling it and the narrator's relationship to the characters in the story. In first person point of view the narrator is a character in the story telling it from their perspective. In third person point of view the narrator is not part of the story and the characters never acknowledge the narrator's presence. Less common than first and third is second person point of view. In second person point of view the reader is part of the story. The narrator describes the reader's actions, thoughts, and background using "you." (Merriam-Webster)
I think that any representation could be a possible candidate. You are too focused on language, when a person can communicate perception in more than one way. Another way is for example art by which a person can in a more direct way communicate what they perceive.
For example people suffering from schizophrenia are a group of person who are suffering from a decay of brain functions during episodes. In those situations they are so to say in a situation which you could name - let's say - closer to death. During those episodes such people are showing a strange connection when it comes to art: They are painting or sketching certain structures or patterns, especially fractal patterns. When it comes to music they tend to produce a certain style of music, like noise or glitch music.
Usually this is explained as hallucination, however some think that people suffering from schizophrenia could be able to see patterns which are normally not perceivable.
Carmen Wrede We can also measure consciousness by how the DNA restores itself. If the individual’s DNA ceases to restore itself, then consciousness is less probable. Preprint Concisely Quantifying Consciousness
Minister Alexander Ohnemus The species Dictyostelium discoideum would like to exercise its veto over this statement, as it is an example of a single-celled organism that does not have DNA but is still conscious. So there are living beings who refute your statement. I hereby represent the interests of the species Dictyostelium discoideum.
Carmen Wrede Excellent point. Each individual member, of the Dictyostelium discoideum species, has its own biological identity. Thus,
to quantify consciousness, note how genetic identity, AND REPLICATOR, varies per individual. Consciousness is the self, illuminating individuality is the clue, AND individuality must be restored for life.
Minister Alexander Ohnemus This statement actually has a certain proximity to ideas of eugenics. The focus on genetic identity and individuals as replicators sounds like a very reductionist view of life that does not take into account the complex connections between environment, genes and phenotypes.
Furthermore, it is problematic to see individuals as mere replicators, as this diminishes the diversity and uniqueness of every living being and can ultimately lead to a hierarchy and exclusion of certain individuals or groups.

I have some difficulty in understanding the question: can only first person reports measure consciousness? However, I assume roughly that it is asking for an explanation of the nature of consciousness with the implication that that so little is known with any agreement or objective accuracy about consciousness that one necessarily has to report to subjective opinion on the subject?
Well certainly, I have been considering the problem of how mind and memory operate for quite some time on a somewhat fundamental level of observation of human behaviour, together with some attempted understanding of physics and some non local quantum effects to reach some subjective conclusions on the nature of consciousness. Rather to my surprise, the latter tend bear out the ancient hermetic saying 'As above, so below' in comparing the mechanism of the motions of certain of the braasi's neurons,with the structure and motion of stellar masses within the confines of the observable universe.
However, this would take a fair amount of explication of the rationale involved, similar in some ways to Sheldrake's thesis of morphic resonance, but I am not sure that would be answer to the question put. However, I have this website, now requiring some updating, where this comparison of the apparently possible random behaviour of the stars might be duplicated by the random firing of the brain's neurons with the state of enlightenment resulting as per vedic beliefs, and in my scenario, from absence of structured thought. My thesis shows how this momentary ability to blank the mind into a random state, is the basis for the exercise of rapid intuitive understanding, and also the initiation of a sequence of relevant memory similar circumstances currently being experienced.
But as I have already mentioned, this would take for to much time to start to explain, but see website for more detail.
First-person reports are parasitic on a public language. Moreover, there is reaction time involved in the delivery of first-person reports. Therefore other correlates of consciousness might yield more accurate measurements. But your question is vague. What sort of consciousness do you have in mind and what aspects of it are to be measured?
