A noble ideal, but that should be the case regardless of where you're going ;)
Then the same rules apply, Use different identities that have no connection to each other at all (none of the same information, email, usernames, phone numbers etc) on my phone I like to have "real" stuff separated into a different profile. If you are worried about a search then you can log out of all your real or fake stuff, depending on what you want to be seen. (I'm assuming the fake stuff should be hidden seeing as they will have your passport). You may even want to clear data for those applications or uninstall them.
YES you should not bring any technological devices with you. In fact it is better to abstain from digital systems for a period of 3 months before entering and after leaving China. (Viruses, etc)
DO NOT think your anus is safe. I had a friend who tried to smuggle in 3tb of Xi Jinping x Winnie the Pooh fanfics by encrypting it with AES-1024 and storing it on micro SD cards in his rectum. Little did he know, that day they had started doing mandatory anus probes on all foreigners. They found it. They cracked the encryption in a few minutes due to Chinese quantum supremacy and needless to say, he was executed on spot.
DO NOT think about the CPC. They have theta-brainwave detectors at the border and can detect revisionist and counter-revolutionary thoughts. Especially if you have any information that could lead to the downfall of the CPC.
Seriously though, what are you expecting to happen? What privacy are you expecting to lose? What laws for discrimination are you expecting to be missing?
When you travel internationally you already lose some privacy in that they have your passport. You are telling them exactly who you are, and where you came from. Some countries will take fingerprint scans (US, China too). Those are pretty big but are not specific to China. You should disable biometrics on your phone though, as that means they cannot force you to unlock it. But regarding the tech on your phone, if you are using any google or meta services, then all your privacy is already gone and Chinese authorities can just buy that information if they want. So I'm not sure exactly what you're worried about, some specifics might be useful.
It would also help to know what you want the cloud storage for. They can't suddenly hack into all of your accounts the moment you cross the border. If you already have sensible security steps like strong passwords and MFA in place, then I don't see what else you'd need to do.
What I'm referring to is that there is not a linear relationships between supplies and GDP. US kit has vastly inflated price compared to what Russia can produce/buy it for.
The cells that encase the nerves (receptors) get infected, and become inflamed. This then means the nerve cells cannot transport nutrients along them, and can't send a signal. Eventually that can lead to death of the nerves as well. This is also the way they found COVID to spread through the brain, not through the nerves themselves but the supporting epithelial (I think is the right name) cells.

Russia seems to be able to keep up this war effort, whilst some NATO countries are already running out of stuff to send. They're getting stuff manufactured cheaply in Iran, North Korea, etc. I imagine the US economy has a sizable proportion made from services. I don't think the US tech sector can make a new app to fight the Russians with. Their cheap war materiel production does not inflate GDP like the US tech or MIC does, but that doesn't mean it is less effective.
If you can find a second hand PC with a Celeron, they're pretty low draw, and it will mean you can open it up and add as many drives as it has SATA ports. We did the same, got an old PC for £30 and added drives and more RAM.
I would definitely still go with containers, running baremetal is less secure, more fiddly and less reproducible
