Maybe combine 3 of your ideas: YouTube, online courses and podcasts are really all the same media: video recordings of educational content. If your expertise is cloud computing and freelancing then start with a video podcast on YT where you separate audio if people want that option only for commutes, etc. They all involve the same workflow I assume and you could use podcast + YT to build awareness about courses. YT vids posted could talk about smaller problems in that space and get enough of them together and you might have a course outline where you can go deeper and offer chat support. Or look at others in the space and do similar but with a freelancer viewpoint. I’m imagining you run into slightly different problems as a freelancer. For example, GKE updates for an employee might be a monthly task they know how to do but as a freelancer your view might be coming in and having 6mo-1yr of updates to apply because they don’t staff an engineer. Maybe the staff engineer warns app teams to change/fix things but when you come in there might be unpleasant surprises waiting because the company has to call in the company that worked on an app to make changes. I have no idea if this is the case, just spit-balling.
