Cheapest subscription to get access to the full font library for web usage?

I want to use some fonts (especially Neue Haas Grotesk, ATF Alternative Gothic) on a website for our company. If I search for them on fonts.adobe.com they don't show up. If I access the fonts.adobe.com website over a google search for the font, the font shows up, but it says "font not available".

We do have a Firefly subscription. As far as I understood (see here), the full library of fonts is supposed to be included. If not, I wonder, what is the cheapest plan, that we could add to use this fonts?

I spent more than 3 hours with different people on the support team and nobody can tell me, why I can't access the fonts or what subscription I should get to get the full access (though one from support suggested, that I those fonts are only included in the most expensive "Creative Cloud All Apps" subscription) .

Best wishes
