When coming from Windows, I can recommend Linux Mint with the Cinnamon Desktop. But there are many more easy (beginner- and user- friendly) ones out there.. In Mint and many other Linux Distros LibreOffice is already installed. I haven’t got much experience with it, but it looks like a great substitute for Word.
As for installing and setting up Linux and Data transfer, check out Joe Collins’s channel: https://www.youtube.com/user/BadEditPro . There you can find video’s on just about anything Linux related.
