--action scheduleNow --code <code> Schedule a job to be executed as soon as possible
--action runNow --code <code> [--tryLock] [--force] Run a job directly
--action wait [--timout <timeout=60>] Active wait until no schedules are running.

Looks like PATH variable is set somehow different in jailshelled cron environment. So I suppose different php binary is used. You can ssh to your cPanel account and set PATH in your crontab.
So crontab should start like:
SHELL=/bin/sh
PATH=/usr/local/jdk/bin:/usr/local/bin:/usr/bin:/opt/cpanel/composer/bin:/usr/local/bin:/usr/X11R6/bin:/home/username/.local/bin:/home/username/bin

Here is something that is hidden in the Magento 2 documentation. Once you install Magento 2 with composer you are not done installing. One needs to go under the /update/ folder and run composer update again so it installs some needed packages for the cron to work properly.
I've seen many Magento2 setups where this extra step was not done, hence everything works except the cron.
If you use command line, it should look like this:
[html]$ cd update/
[update]$ composer update
