The Allies did face resistance upon entering the beaches despite having conducted bombing raids on the defenses prior to the operation. Nobody realistically expects the PLA to mop up 100% of the defending forces prior to going in, but any fighting should be limited to sporadic pockets rather than a coordinated defense like what the Germans put up.
Yes, the D-Day landings faced some resistance.
I also expect PLA landings to face some resistance.
However in the case of D-Day, the extent of resistance, and more importantly, the extent of the counterattack that they faced was significantly reduced compared to what Germany had in store for the allies.
Similarly, I expect the PLA's bombing campaign to significantly reduce the ROC military's extent of resistance and their ability to counterattack as well.
I say this, because what you wrote before -- wiping out most of the "aircraft, C&C centers, airfields, naval vessels, and military staging areas or depots" -- is obviously very sensible and is entirely expected for the PLA to do prior to an amphibious assault... but even having done that, whatever beach/es they choose to land at are obviously still going to face some degree of coordinated resistance as they reach the shore.
