Cash.

VoIP instead of cell service. VoIP is kyc but I can use it without celltower tracking. I keep my phone in airplane mode.

GrapheneOS and lots of Foss apps.

Every account gets a unique login - name, password, email alias. I also give as much fake information as I can. 2fa when it available.

I have no accounts with any of the big tech.

I’m planning on buying a used Windows laptop and installing Linux. Pop_OS to start as I have an eBook on that os.

Edit: corrected autocorrect.
