There is plenty of guidance about how to design inclusive presentations and handouts (I love Microsoft's accessibility checkers that have appeared in Word and PowerPoint in recent years). The Government Digital Service have some good posters on designing for accessibility: accessibility.blog.gov.uk/.../
I think the best way to sum up good practice is that... good course design is naturally inclusive. All the "adjustments" you make should make it better for everyone, not just people who ask for adjustments.
