My W10 PC is a pure gaming and entertainment and VR rig.
For sensitive, critical, financial, shopping things, I have a fast laptop with Linux Mint.
I use an old smartphone
without simcard as bicycle navigation device. My active smartphone I almost never have with me anymore when leaving the house.
I avoid paying with plastic. I have plastic cards not even in my wallet. I have my smartphone not set up for paying with it - no connection to banking accounts on a smartphone, please.
We agreed to wear invisible golden harnesses. But golden or sweet or not, a harness nevertheless is a harness -
and somebody else holds the line in his hand.
Only what is not stored on a smartphone or in the "cloud", cannot be stolen , abused or tracked.
