问题
I recently installed Fedora 24 Workstation on my desktop and was able to install everything without issue, until I tried to install steam (from rpmfusion) and wine. Both steam and wine have 32-bit dependencies of libraries that are already installed in 64-bit and used by other, more important programs. Typically, this shouldn't be an issue, but it turns out that all of the doc files in /usr/share/doc or /usr/share/licenses, etc are causing conflicts upon installation of the 32-bit version of the libraries. What is my best course of action here?

There is special magic which allows files from multiple archs to overlap if they are identical in contents and metadata. But, from your example, you have many lines like this:
file /usr/share/doc/glibc/NEWS from install of glibc-2.23.1-8.fc24.i686 conflicts with file from package glibc-2.23.1-7.fc24.x86_64
file /usr/share/licenses/libpng/LICENSE from install of libpng-2:1.6.23-1.fc24.i686 conflicts with file from package libpng-2:1.6.21-2.fc24.x86_64
Note the emphasis I've added — the versions don't match. This means that even if the files are identical, they probably have different dates — which means you get conflicts.
Solution: update your system before installing the i686 packages.
If you happen to be in a situation where the existing x86_64 packages are newer, which could also happen, that means the i686 mirror you are hitting is out of date — but since that's a different problem, I'll leave it for some future question. I just wanted to mention it as a possibility for completeness.
Note that in this case, the problem is conflicts. We had a situation a year or so ago where the package state was such that if people didn't update and then installed newer i686 packages, they actually hosed their systems. That was a bug and shouldn't have happened — but the general practice of "update before install" would have avoided it.
