Linux comes in a million flavors but most people should start with Mint. That sounds like a pun, but it's also true.
Mint is a nice, safe, up-to-date, simple, Windows-like choice that won't unnecessarily complicate the transition to an entirely different operating system. It has good hardware support and good defaults. Most things will feel very familiar and be very accessible. It is popular enough to find plenty of help on the internet and answers to almost every question you could have. It mostly just works and when it doesn't it's usually not a deal-breaker.
It's not my favourite distro, but you aren't ready for my favourite distro. Honestly I'm barely ready for my favourite distro. It's not elitism, it's just practicality. You'll learn as you go, and you'll eventually want to try other distros, but start with Mint, and keep a Mint system around for when you break everything else. Which you will if you start playing with other distros.
