For dealing with .docx files I would recommend OnlyOffice. It's a FOSS office suite, but unlike LibreOffice, it uses the .docx format natively.
I read a comment about this a while ago, but basically under the hood LibreOffice does everything in .odt etc. and it has to convert the files first, which can lead to the format breaking. The same goes for OnlyOffice and .odt files, as it only uses .docx etc. under the hood.
