Thanks so much for the informative and detailed reply. That pretty much answers every question.
Thanks also for the tip about LMDE. I actually really like Mint, I’m only switching because it’s the only distro I’ve tried and I feel like I should shop around a bit. Going to Debian because while starting my journey I want to shop around with things that work, rather than having to learn how to tinker all at once just to get things running. But if I decide I need Mint back I’ll probably check out LMDE for the hell of it.
You mean “they,” right?
