Above examples are for '*', to catch EVERYTHING. I'm going to wind up with an unknown number of files in /tmp/ called file_sw_list, file2_sw_list, etc. etc.

Piping the * through ls accomplishes nothing you couldn't have accomplished without it, except possibly scrambling any filenames with whitespace in them -- backticks split across all whitespace, not newlines.
It would be a pretty freaky coincidence to wind up with filenames matching my pattern with whitespace... they're generated from unquotes variables. It could happen, and I always like to sanity check as much as possible, but that's pretty far down my list of worries.

...or even:
Neither work. I get the same result.

What does the '' do? I don't understand the meaning of the blank expression, but if you say it works...
Two single quotes, not a double quote. I'm performing the operation on a file, and don't want a "backup". BSD sed is picky about this stuff (OS is OSX).

Why are you escaping a space?
Because there's a literal space in the pattern I'm matching?
In any case, it turned out to be a second pattern that matched '^Software\ Update' that was so close to the top I didn't notice just a couple of lines missing :-)
I have tried everything I can think of to get sed to change line N of a file to the contents of a variable. I have Googled the Internet, and I find lots of people telling how to use variables with the "Substitute" command, but no one telling how to use variables with the "Change" command.

atf-sh
ATF-SH(1) BSD General Commands Manual ATF-SH(1)NAME
atf-sh [-s shell] -- interpreter for shell-based test programs
SYNOPSIS
atf-sh script
DESCRIPTION
atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library.
atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL. atf-sh executes the inter-
preter, loads the atf-sh(3) library and then runs the script. You must consider atf-sh to be a POSIX shell by default and thus should not
use any non-standard extensions.
The following options are available:
-s shell Specifies the shell to use instead of the value provided by ATF_SHELL.
ENVIRONMENT
ATF_LIBEXECDIR Overrides the builtin directory where atf-sh is located. Should not be overridden other than for testing purposes.
ATF_PKGDATADIR Overrides the builtin directory where libatf-sh.subr is located. Should not be overridden other than for testing purposes.
ATF_SHELL Path to the system shell to be used in the generated scripts. Scripts must not rely on this variable being set to select a
specific interpreter.
EXAMPLES
Scripts using atf-sh(3) should start with:
#! /usr/bin/env atf-sh
Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh. Instead, you have to hardcode
the path to atf-sh in the script and then use the -s option afterwards as a single parameter:
#! /path/to/bin/atf-sh -s/bin/bash
ENVIRONMENT
ATF_SHELL Path to the system shell to be used in the generated scripts.
