After a security wipe, my z3 is not syncing with Google contacts, how to get fixed?

You will need to configure the account manually.
First, remove the existing contacts account (if it's still there), then go to your Google account and ensure 2FA is disabled and also make sure the so called "allow less secure apps" is enabled.
If you wish to leave 2FA enabled, you can also create an app password and use the created password for step # 6.
Now follow these instructions carefully:
1. Go to Accounts.
2. Select Add Account.
3. Select Advanced at the bottom of the screen.
4. Tap CardDav.
5. Enter whatever you like for a description,
your Gmail address for username,
and Gmail address for the email address.
