I pondered a lot including a bit about rpmfusion in Fedora’s paragraph, but I elected not to because there is already too much stuff here :D
As a 20-years Debian user who switched to Fedora a couple years ago on my main laptop, I would say confidently that Debian is the distro I’m the most comfortable with. I love Debian. But, there are a couple things that prevent me from recommending it as a very first distro:
The base system is very barebones and you’re required to manually install vital things like proprietary drivers (I think it’s a bit more painless now with the nonfree installer but I haven’t installed a fresh Debian in a few years). For me, having a fully functional Debian laptop is not hard work but requires a bit of knowledge beforehand.
A lot of people want the latest and shiniest, and with Debian might be tempted to switch to Testing or Sid which is a very bad idea for a daily driver.
