which programs benefit the most by cron (for a SOHO user)?

I understand that cron is basically a job scheduler. Apart from doing $sudo apt update which I like/love to run manually as it’s uncertain when my bandwidth will be free for running the update, I don’t know of any programs which would be useful to run via cron. In a SOHO environment, where I don’t run LAMP, is crontab useful, if yes, which programs would benefit from it ? Are there any user applications which would benefit from it being in cron ?

I am on Debian.
