Very good choice going with Debian. It is simple, clean, can be as minimal or as “bloated” as you wish, and once you’ve worked out the kinks it will happily run for years without maintenance (except updates of course).

There’s a steep learning curve because as a user you’re expected to configure stuff yourself (although defaults are most of the time very sensible), but if you’re willing and able to truly learn Linux and the terminal and you’re familiar with your hardware, it’s one of the best platforms out there.
