Before jumping from one powerful word processor to another, you might try something simpler and see if it works for you. I'm a huge fan of Typora, which is a clean, minimalist app that lets me focus on writing and not on aligning bullet points or tab stops. It works on Windows and Linux. It uses markdown for formatting like boldface (easy to learn), and it can export to Word, PDF, HTML, and other formats, as well as importing Word etc.
I agree with people who say using a GrapheneOS phone for a while is a good step toward Linux. You get used to using a lighter, cleaner system on your phone, and you start to want the same experience on your computer.
