The web servers have nginx + php-fpm and handles incoming web requests.

This setup will make sure that you will only get one job per 5 minute since there is only one machine that is pushing it. This setup will also make sure that the cpu load generated by the workers aren't affecting the web requests.
One issue with my answer is obvious; that single scheduler machine is a single point of failure. If it dies you will no longer have any of these scheduled jobs dispatched to the queue. That touches areas like server monitoring and health checks, which is out-of-scope of your question and are also highly dependant on your hosting provider.

Regarding that little asterisk; I can make up weird scenarios where a job is executed on several machines. This involves jobs that sleeps for longer than the timeout, while at the same time you've got an environment without support for terminating the job. This will cause the first worker to keep executing the job (since it cannot terminate it), and a second worker will consider the job as timed-out and retry it.

A:

Since Laravel 5.6+ you can ensure your scheduled tasks only run on a single instance using the onOneServer function e.g.
$schedule->command('loggingTask')
            ->everyFiveMinutes()
            ->onOneServer();

This requires an APC or Redis cache to be set up because it seems to use a mutual exclusion lock, probably RedisLock if Redis is set up.
Using a queue you shouldn't really have such a problem because popping a task off a queue should be an atomic operation.
