All mentioned functionalities can be achieved by most word processors. OpenOffice.Org for one handles all mentioned requirements. Additionally, I believe you can use the database capabilities of OpenOffice to produce different documents if the hundreds of documents you're mentioning can sit in the same format with different inputs out of the database. That requires a little bit experience to know how it works.

Microsoft Office, (Apache) Open Office, LibreOffice (Yes, it is the sole heir of OpenOffice.org) and Google Documents represent different views of word-processing, office documents and typography.Microsoft Office keeps going its way — nice features, but bad compatibility, neither with Open Document Format nor with its own formats — yes, even Microsoft Office can’t be compatible with itself. Though the Microsoft OOXML got ISO29500 as an “international standard”, but Microsoft Office has poor, non-standard and different implementation of OOXML in every different version Office. That made two people with different versions of Microsoft Office, say Office 2007 and Office 2013, can not exchange their docx/pptx/xlsx because Office 2007 can not open files generated by Office 2013, which shouldn’t happen if OOXML *is* an international standard.(Apache) Open Office is simply dead. (Well, I know that maybe someone would argue this, but that’s my point of view) LibreOffice is currently the sole heir of OpenOffice.org, inheriting its community, its spirit and its value. LibreOffice follows Open Document Format and hence every version of LibreOffice can generated the same standard ODF files and have the best interoperability. The features are quite different from Microsoft Office, but the fundamental ones are always there — all the features for paragraph format, paragraph/characters/page style, templates, tables, forms, mail merges, spreadsheet functions, pivot charts, animations and graphs in slides, … are there. They may just implement and present in a different way from Microsoft Office.Google Document (Google Drive) is a good collaborative tool and is useful *when* multiple users need to edit a document/spreadsheet at the same time. However you need to be noticed that it is a public cloud and remember not to put *any* sensible / private data — no matter for work or for your own data — there. No privacy is there. Office 365 is the same — see Dutch government report says Microsoft Office telemetry collection breaks GDPR | ZDNet .So, the answer to your question:If the data privacy is important to you, don’t choose Google Docs / Office 365. Use offline version *or* online version with private cloud like Nextcloud+LibreOffice Online. The experiences of the latter may not be as good as Google Docs but it can protect your data well.If the interoperability (when you must be sure that the receiver of your documents can open, read and edit your documents without problem, use LibreOffice and Open Document Format. Google Docs is also a choice if you don’t mind your data being sent to somewhere else.If you just create documents for yourself only, i.e. no interchanging or collaborative editing is needed, then the tools don’t matter, which means — at least for me — no reason to buy a Microsoft Office suite and use only 1/1000 of its software and features.
