My user name tells you what I think about cis!
I am a woman, an adult human female. This is the word to describe my actual, physical biology, my reproductive system, not my clothes, hobbies or personality.
I am not a 'cis' woman, because that simply does not make sense. I can never be 'on this side' of woman, because 'woman' doesn't have sides. I will always be a woman, regardless of how masculine or feminine I appear.
Cis woman is not the opposite of transwoman. Transman is the opposite of transwoman.
Transwoman is not a subset of 'woman'. Transwoman is a subset of man.
If you want to specify whether a woman is trans or not, you do not need the term 'cis'. Woman and transman covers this.
If you want to discuss a woman and, say, Paris Lees, then 'woman' and 'transwoman' covers this.
You might well need to divide women into subsets such as old/young, rich/poor etc if you are comparing different adult human females, but 'woman' does not need any sort of prefix if she is being compared to a man. The word 'woman' says it all.
