Subcommands vary unexpectedly. E.g.,

• for picking up a url set in $SAWTOOTH_HOME/etc/cli.toml instead of --url
• parsing option -F as short for --format

then

• identity and settings don't do those
• block, peer, and state do those.

It's probably worth reviewing the command-line arguments across sawtooth's subcommands to look for easy opportunities for unification. With luck, some of this is a bit of copy-and-paste that can be factored out to a common helper.
