Yup. And China could physically isolate Taiwan in a way that Russia could not isolate Ukraine.
Taiwan would need to absolutely prevent a succesful landing in the first place. Once China got a secure beachhead or airhead that they could hold, that’s the ball game. China would probably be willing to spend its young men profligately to achieve that lodgement. Would the US go to war with China to stop it?
Respectfully disagree with your last point, re China would probably be willing to spend it's young men profligately

China has some massive population problems, and they know it.
- Recent estimates have put the Chinese population at roughly 400 million people
less than what they thought they had...
(That's more people than Canada & the USA combined!)
- With the longstanding one child policy replacing 2 parents with only 1 offspring, the state aimed to cut it's population in half.
That's population collapse Number 1...
- But because culturally they tended to favour boys, their population demographics are heavily skewed in favour of men.
(Which means a lot of those men won't ever marry or have kids, effectively ending the lineage of countless families.)
This is population collapse Number 2...
China is well aware of this pending population reduction, when the 2 parents both die & are replaced by only 1 child. They are well aware of it because this was the whole point of the policy in the first place.
They
NEED those 'children' to make their society function & to take care of the older generation as it ages & passes on...
They
DO NOT NEED some unnecessary war that will inevitably kill, at the bare minimum, tens of thousands of the very young people they know they will
NEED as time goes on.
So I don't think China will just send human waves to die willy nilly. They have enough challenges incoming as it is.
...
I also think China is
well aware of the effect their informational warfare campaign has had & is having on the general Taiwanese population - young people inparticular.
I think while patriotism is probably fairly strong among the general public, Taiwanese leadership should absolutely factor in the very tangible effects of the PLA's information efforts.
At the rate their going, I think China could quite possibly reunite with the island without ever firing a shot. China plays the long game, and their desire to reunite the island may come to fruition with the next generation of Taiwanese being much more open to reconciliation.
Between a population that's been bombarded with subtle yet impactful propoganda from a young age + Chinese intelligence officers undoubtedly floating around key parts of the Taiwanese government and military - I think it's a very real possibility that Taiwan will fold in the end due to soft power, information warfare, and subversion from within.
