I am more familiar with "Pwd" as an abbreviation, but do we need to abbreviate this at all?

What did you mean by "mimic the field name in the config"? There is no Psw field in the configuration file.

The field can be named "Psw" for consistency with old code (or all renamed to "Password"), but the CLI argument should be named -tidb-password not -tidb-psw.
