traditional crontab from /etc/cron.daily/job, ... ?
As I said before, I mostly use cron due to muscle memory, but it seems
systemd timers have more useful features.
For example, "what is going to run next, when? Also, what has run, how
long ago, what were the results?"
One could use a tool like those from https://crontab.io/ if using cron.
Or, systemctl list-timers (composing in HTML to get fixed-width font):
