I've used debian for almost twenty years and arch for over half that, despite being comfortable with Arch, I would not sleep well at night if anything mission critical depended on it. You install a rig with Debian on it and touch nothing, it will last longer than you.

No, it will not last longer than you. If you want security updates, you have to do major ditro upgrades when the support for previous Debian release is over. And these are somewhat tricky.

You'll just have your upgrade dance clustered into a single event once every N years, instead of spread over randomly, based on major releases of SW your server depends on.
