Best ways to recommend articles based on labels?

I'm hoping to get some guidance. We want to try to give people access to the articles they probably need, ideally before submitting a ticket, whether using the chatbot, suggested articles, email autoreplies, etc. The thing I'm getting hung up on though is recommending articles based on a specific tag or label without me manually entering each article I want to recommend.

Ideally, any of the following would work, but I haven't found anything to let me do roughly what I'm after:

• On the New Request page, specify suggested articles based on the specific request form (can't seem to find any way to tweak these suggestion settings)
• Using the conversation bots to recommend articles based on a tag (have to enter articles manually, and only 3 per step)
• Using conversation bots to link to a Guide search for the content tag (looks like this can be done, but I need to find the content_tag IDs manually to make the links, which is fine for 1 or 2 buttons, but we've got many more to do)
• Email autoreplies based on the form to include articles with a given tag/label

Does anyone have any idea how we could go about getting the results we're after?
