I'm not sure that's the case with Xi. Well, I wouldn't be surprised if he tries, but as far as I can tell from a distance, his value system produces unwise decisions long-term. 10+ years of Xi have slowed economic growth, produced antagonism diplomatically, I'm not sure that the Belt and Road is currently seen favorably. He hasn't figured out a way for local governments to be solvent without selling property, nor has he resolved the shadow debt. I think his policy of shutting down Shanghai and other zero-Covid polices destroyed the people's confidence in the CCP as steward of economic growth, as it became obvious that the government can just arbitrarily kill your business and imprison you in your own home or Covid center. I think that removing your top military leaders--who are the only ones with any actual combat experience--is helpful for a successful occupation of Taiwan. Certainly what Xi did with Hong Kong made peaceful re-unification with Taiwan very unlikely.
The policies you're naming are still enacted for their expected long-term consequences. That doesn't mean all of them are successful in achieving their goals, sometimes their expectations turn out to be wrong. This can happen with any policy, regardless of whether the goal was short-term of long-term.
If you're talking about the power shift part: Many if not most (including me) believe that slowing of economic growth was inevitable, it simply wasn't a level that could be sustained in the long run. There are plenty of issues in China and plenty of policies that may turn out to have failed - much of it remains to be seen, as again, the goals are long term and we may consider them successful a decade or two from now. But the scientific gap with the rest of the world is widening every day, China is crushing it in that area and the fruits will be reaped. Robotics, every kind of energy, every kind of engineering.

It didn't have an impact. By 2019 the chance was already zero barring black swan events. The chance is still zero barring black swan events.
