what about Fedora workstation for the old-lady use case? I'm about to give my 12 year old non-technical daughter a linux laptop, and wondering on distro. I'm thinking Fedora but open to be convinced otherwise?
For the old ladies, no: Fedora has a short release cycle, and no LTS; not great for maximal stability. "a version of Fedora is usually supported for at least 13 months" ( https://endoflife.date/fedora ), while Debian is security-supported at least 5 years! ( https://endoflife.date/debian )
Debian's whole project architecture & release cycle is built towards being stable bedrock, I see virtually no reason to use anything else if you aim at max. stability and don't care about running old (but still secure!) software.
