For kindle paperwhite, the main formats are pdf, mobi, azw3(kf8), kfx, and generally when converting books for kindle, it's best to convert to azw3 right?

I hear that while kfx is a better format and provides better typesetting, isn't extremely reliable as some books will have difficulty being converted to this format correctly, is this true? If so, I guess azw3 would be the better way to ensure quality and reliability?

1. is calibre what i should use to convert pdf to azw3?
2. can I (should I) convert mobi to azw3?
3. what are some of the essential plugins and tools that I should get? what's a good de-drm plugin? I hear people using hyphenate plugin, is this useful at all? what are some other plugins that you would recommend or considered essential for an avid reader/kindle user?

thanks in advance
