What is the water in the Taiwan Strait like? Clear or muddy?
The Baltic Sea is very good for submarines to hide in, although being deeper than 150 meters only spot wise, because it is muddy with very poor sight. The Persian Gulf on the other hand is so crystal clear with its sand floor that there's nowhere to hide.
G.U.P.P.Y was not a class it was a program. The Greater Underwater Propulsion Power Program that was down across multiple classes. The Balao-class former USS Tusk now Hai Poa and the Tench class Former USS Cutlass now Hai Shih.I think you mean Guppy Class, the last American made diesel electric submarine.
I think it is a simplification to assume they would just operate in the Straits. They could be used to enforce an Exclusive Economic Zone or target shipping lanes of an invading force. Or they could do like the Israelis do with their Dolphin class submarine and use them to carry sub launched cruise missiles to have some sort of second strike capability even if they just used conventional warheads it could be enough to sink a ship at long distances especially with outside satellite intelligence. Heck given the costs of satellite launch now they could even orbit their own observation satellite in a geostationary orbit to provide 24h panoramas of their defensive perimeter.
It would provide them with more options. But I still think their best choice would be to "turtle", like we usually say in strategy games, and just add gobs and gobs of land based missile defenses in protected or mobile positions. Basically what Israel did with Iron Dome and what Russia did in the Baltic.
Oh, some people forget, but the major losses the German Navy sustained in WW2 during their Norway campaign were against some XIXth century vintage Austrian-Hungarian torpedos in a Norwegian fortress in a channel. The Norwegians sunk two ships with that and this resulted in the German surface Navy being consigned in port or in bastions for the rest of the war. Quite pathetic really. Still it goes to show that even just torpedos can be deadly in the proper conditions like in choke points.
I think it was Curtis LeMay who once said, paraphrasing, that a good way to avoid getting into a war with someone was to make it so grievously expensive to the other side to start a war that they would basically not even begin one. Carriers and Type 055 cruisers are expensive. So the submarines could aim for those. But more likely, they could do unrestricted submarine warfare, like the Germans and the USA did in WW2. The USA broke the back of the Japanese by sinking all the merchant ships they could find. The Japanese ran out of oil and rubber and it ground their war machine to a halt. They could just blow up all the oil tankers and cargo ships they could find. Which would take years to replace. In case of an invasion of Taiwan, they could then move the submarines to friendly ports, and continue the fight from there. The beaches could be either mined or bombed in case of invasion.
Also a lot of people forget, but Taiwan isn't exactly flat, it's not like it's Poland:
If the Taiwanese put up a real land based resistance it wouldn't be over in a couple of days. In the worst of cases, the USA could do a nuclear warhead share agreement similar to what they have with Germany and Turkey with the B-61, except with Tomahawk warheads. Imagine the Taiwanese get diesel-electric submarines which can fire conventional armed Tomahawk missiles, optionally nuclear armed, with the nuclear warheads under US supervision under a similar program.
These are all hypothetical but this is not an unrealistic future scenario.
