I don’t think that there really can be cannon for media projects with this many different leaders at the helm, made so far apart, and without a strong source material. There’s so much media to watch out there that if I don’t like a show, I am not going to watch it just because I liked other shows with a similar naming scheme.
There is also a lot of time travel and “mirror universing” in Trek, so whatever could be considered cannon might not have happened in the same timeline as other events that are also considered cannon.
