e.g. What does "rm -f /tmp/*" do if there are 12,000,000

Whereas "find /tmp -mindepth 1 -maxdepth 1 ! -type d -print0 \
| xargs -r0 rm -f" will succeed. More
complicated, to be sure, but more robust.
In this case I guess
find /tmp -mindepth 1 -maxdepth 1 ! -type d -exec rm -f {} \;
would work just as well and is less complicated or am I missing something?
I'm not 100% sure your find will cope with a filename with spaces in it.
Might be a portability issue if nothing else.
The big difference is the xargs version will group files together making
far fewer calls to rm whereas your version invokes a new rm for each file.
That could be a big efficiency hit if there are truely large numbers of
files involved.
Filenames with spaces should work with -exec.
Newer versions support "-exec cmd {} +" instead of "-exec cmd {} ;",
which behaves like xargs, it will run the command with multiple filenames.
