(ALSO ADDED TO THE ORIGINAL POST)
These resources really helped me when I hadn't done any job hunting in 11 years and was super rusty and out of practice:
https://youtube.com/c/DonGeorgevich - Don Georgevich: Job Interview Tools
https://youtube.com/c/ALifeAfterLayoff - Bryan Creely: A Life After Layoff
What I'd recommend with these two YouTube channels: Just search through the videos for each of these channels for ANY topics that directly interest you the most. It could be about résumé writing, could be about cover letters, it could be about what interviewers are actually looking for when they ask you certain questions, it could be about career changes. There's enough content on both channels that you can just pick and choose what's interesting for you.
So don't feel pressured to "OMG, watch every video", but when you get some breathing room, scan around and dig in.
For all jobs, order the skills/impact bullet points in the order of relevance to the type of job you want, i.e. if you want to manage people, put any managerial experiences first; if you love reviewing contracts and data, list those kind of actions first; if you love solving problems, put the instances of product development, tool creation/metric measurement innovation first or customer service experience. In other words, steer your relevant experience towards what you want going forward, and de-emphasize other stuff.
Include any professional development accolades, e.g. formal trainings, certifications, presentations. If you have anything like that, that’s relevant.

Lists of overused résumé terms: https://www.capstoneresumes.com/remove-25-words-from-resume
Without overhyping yourself or using words you wouldn't normally say when casually speaking, use more of these impact verbs instead of more passive and generic verbs like "provide", "support", “work with”, and “assist”. In other words, stay true to how you communicate, but put yourself in the best possible light with verbs that you like from the big list.
You'll need to add placeholders for numbers you would fill in to help demonstrate impact.
Good résumés convey your IMPACT at your jobs, not just the list of responsibilities.
Your aim is to illustrate:
1) how you left each job better than you found it; and
2) what hard & soft skills you demonstrated to do it.
What specific things did you accomplish? How did you make money or innovate for the company? How did you make things more efficient or effective?
That said:
1) If a number wouldn't be impressive (i.e. typically 10+), then don't include it.
2) NEVER ever overstate a number. Always underestimate while giving your best guess if you don't remember something more specific (e.g. "worked with 300+ customers"). If you overstate, you risk the company contacting an employer and them being told you've embellished/lied.
3) The numbers usually should represent total impact (e.g. if you did customer service at store for 5 years, you should say either a) approximately how many total customers you worked with over the years or b) how many customer, on average, you worked with per year).
