just trying to get a good mental model of when it's reasonable to use tools like awk instead of simpler unix tools. also further confirming that sed is almost never the best tool except for substitutions.

Sed and awk have a lot of overlap. Another thing to consider is that neither might be the right choice if you are inside a bash script since spawning a new process in a tight loop can be very expensive and bash's built-in regex operations can have much better performance in those situations.

Ok, I would say... cat is mostly used for output of files, and concatenating files. sed and awk are good at reshaping the output of files or piped std input. They both require some time to learn, but it is worth going back to them.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
