Some of the letters are consistently struggling to print properly, like a, w, q, etc. I've cleaned the typebar section multiple times which seemed to help initially but it continues to be an issue, I'm not sure what could cause only certain letters to print incorrectly.

Issue with light imprints on a, w, q, etc.
Are you a touch typist or a two finger hunt-and-peck typist?
Solely based on the letters, I'll guess there's nothing wrong with the machine and that you're a newer touch typist whose two weakest fingers on your non-dominant hand just need some exercise to get a better imprint. I'd guess the same happens to your z and x as well, but you use them less. Practice typing about your "qwaze axes and saws" a few times a day for a week to improve your finger strength and technique.
If you're a hunt-and-peck person, then your typebars may need some gentle forming/fine adjustment using some specialist tools to give better imprints. Those letters on the ends of the segment more often go out of alignment than others. If this is the case, try: https://site.xavier.edu/polt/typewriters/tw-repair.html
