> The only issue with linux I am wondering about is sharing my CV where most companies need a word file.
Maybe it's regional, but I've never been asked for a Word file resume.
I've never had somebody turn down a PDF. And all of the "Upload you resume" online applications I've seen also support PDF. A lot of them lately will even correctly parse out the info and auto-fill forms with it, but some of them mangle it.
For CV I use libreoffice and save it as a PDF/a. If it needs to be editable for some reason you can use docx or odt(odt might scare the average office worker so stick with docx).
I've also heard that OnlyOffice is very good and has better compatibility with Microsoft's formats, but I've never personally used it.
