I often find myself in the same boat! If you're looking for resources, I recommend looking up "a11y' https://www.a11yproject.com/resources/#pdfs this is a link to resources on making PDFs accessible
yus! a11y is v neat! I oughta look more into them since I'm doing more alt text work <.< Illinois State University (which I know nothing else about) has a great resource for using Adobe Acrobat for accessibility, tutorial videos and all~
