Aka How can I improve accessibility in the existing PDF files without re-creating those?
Adobe Acrobat Professional comes in handy if you want to modify/update your existing PDF documents without re-generating it from the source files. While PDF documents are for consumption and are a final output without much scope for large-scale editing, Adobe Acrobat does allow you to do different types of edits, including but not limited to, editing text, editing images, manipulating backgrounds, manipulating watermarks, adding or modifying numbering, and so on. Another set of under-the-hood manipulations allow you to make your PDF documents accessible and help differently abled people consume the content. This also makes your PDF files more search engine friendly.

Add Document Properties and metadata
The following videos by Sally Cox, is a hidden gem. It describes in great detail where to find which properties and how to update open settings, metadata, and other Initial View. She also illustrates the change by showing before-after scenario. The 10 minutes are well spent, but view it with a mental state to learn.

Watch the following video to get a very quick look at just how to add alt text to an image.

Act on the detailed accessibility report
You can check the accessibility by running a full blown accessibility check on a PDF document. Two videos I think are useful to know how to run the report and act on it are below:
