China Uncensored did a video on what an invasion of Taiwan would look like
Based on this article:
The first one is a blockade of the Island. But then China would be sitting ducks for the rest of the world once the calvary comes running in.
The second, china strikes taiwan with missiles and storms the island. And the rest of the world is playing catch up.
The last one is the second option, on steroids. They still storm the island, but also attack Taiwan's allies at the same time. Both physical and cyber attacks. Basically, distract the US, et. al, from coming to Taiwan's aid by causing issues elsewhere.
The last one sounds like pure fiction tbh. It reads like something from a Jack Chick tract. They might do some physically or cyber attacks. But not both at once. The article mentions the possibility of China activating cells it has of nations within the US and elsewhere.
But then again, if they do go with the last option, it could leak out. Ala the Zimmerman telegraph. And then the US would have a reason to rally the rest of the world to sanction China and impose large tariffs on them.
Possibly russia as well. Russia owes china a solid.
