Make Word and Excel open files from my hard drive by default

In recent versions of Word and Excel, when I press cmd-O or select Open from the dropdown, it gives me an annoying cluttered screen full of options I don't care about instead of actually letting me open my files. To get the latter I have to click "On My Mac", down under "Other Locations". Is there any way to make it just open the files from my filesystem by default, the way it used to until recently? I saw a related question that recommended deleting the OneDrive app to make My Mac be the default for saving. I do edit shared files in SharePoint/O365 at work, so I'm worried about that getting screwed up. Is there any other option? If deleting OneDrive is the only option, what will it do to my SharePoint workflow? If I have to live with this dialogue box, I guess it's not the end of the world, but it *is* really annoying so I thought I'd at least check if anyone had ideas.
