Taiwan is also an island separated by hundreds of miles of ocean from the mainland. Russia shared thousands of miles of land border with Ukraine, much of it flat steppe. China's ability to make meaningful changes in Taiwan would be difficult with it's own boots on the ground, and it would be far harder to to that in Taiwan than Russia doing it in Ukraine.

You seem to forget that Ukraine has hundreds of km of borders with NATO countries (Poland, Slovakia, Hungary, Romania). Refugees go out, military supplies go in. How would that happen in Taiwan.

Yes, there's no direct land route for Taiwan's allies to use, but the same is true of Chinese forces trying to get onto the island. Their supply routes may be shorter than Taiwan's, but they are just as vulnerable. Both sides are likely to suffer a majority of their losses just trying to supply their troops, and the effectiveness of submarine warfare against enemy shipping and air superiority against enemy airlifts will determine victory in the long run. So long as the West maintains superior submarine and carrier fleets, they offset the longer supply lines. If China catches up in either or both of those areas, the advantage of shorter supply routes starts to tilt in their favor.
