Reporting advice

I have been given a task to merge 2 reports, currently created in word and powerpoint respectively.  The 2 reports are used to update a board and are quite similar to a highlight report.  The word document is a text update and the powerpoint is a mixture of text and statistics.  I need to combine these reports into an easy to use/read format.  My question is, is there any O365 apps that can be used for reporting, that is easy to use and navigate?  I have looked at sway, but i do not think that is appropriate for what it required. 

The brief i have been given is as follows - 

The purpose of these documents – primary function is for project lead to prep for board meetings.  The document is used to communicate key points/considerations – the format needs to be helpful in this and not a distraction.

Whilst the above is the primary driver - the document must also be efficient for us to use (simple/easy to navigate/sufficient space)

There is no preference on format or software used, but the ‘customer’, needs to be comfortable with the document, before it can be implemented.
