Here is my take:
The most likely scenario, for me, is that sometime before 2049 the people of Taiwan, in a referendum, vote for Reunification. No one gets killed, and no one can really complain. All China has to do is keep developing and this should happen naturally.
If there is to be an invasion, I doubt that some scenarios here are realistic.
Why would China destroy infrastructure, fabs or any other valuable civilian assets? They want reunification, not destruction. They want to integrate Taiwan, not have to rebuild it. I think they would focus on the Taiwanese military and leadership
EW, Cyber, Sabotage, Spy’s and (Taiwanese) Traitors could disable a lot of the Taiwan military effectiveness at the right moments. China must have a lot of human assets in Taiwan. Perhaps they could stage a coup? Also a bloodless way to end the situation.
Otherwise, as many noted, China will need to get “boots” on the ground as quickly as possible, but perhaps not in the traditional sense. The trajectory of UGV, UUV, and UAV surely means they will be doing the most dangerous work, in the most dangerous places, like beaches or minefields. Perhaps the PLA soldiers will be doing the initial landing from the comfort of some shipping container somewhere.
I think we will see some pretty unconventional tactics due to advances in technologies. I would like to see innovations in underwater or even underground delivery of forces as well as direct deployment from the mainland as an alternative to the 071 and 075 fleet which is at considerable risk from AShM missiles launched by bombers far out at sea as well as subs, mines, torpedos etc.
Only in the event of resistance, some bottleneck or hold up, should China really pound the localized resistance. The war would only be won once Taiwan is on board and in a better situation than before the war. As someone said, this reunification is era defining.
China will want to show how they preserved as many lives as they could, while at the same time going for a rapid finish, which makes me think they will focus on the political leadership by going for decapitation strikes at zero hour followed by Sabotage, Cyber, EW, Information/Propaganda and immediate boots on ground delivered by surprise tactics.
This gives a shot at immediate victory, at very low cost in lives. Money isn’t important, these weapons have been bought and paid for with the intention of using them in this scenario, China likes using their weapons and uses them up in training happily.
