Have you explored the simplest option: separate "Weweb for devs" and "We web for marketers" landing pages, videos and homepage subsections/columns/tags?
On the video: first impression is that it's heavily Weweb-built template driven like another Squarespace (especially if I stop watching in the first couple of mins before the bit about design systems) whereas I assume from the description in this thread that the design elements marketers can add and what layouts/colours etc they can choose can be fully configured by devs (and the target audience is teams that want to do this) Ultimately I assume you plan on replacing the tutorial on the home page with a video that's snappier, more benefit-focused and more selective about UI examples anyway?
