First of all, the best to your dad and you. In answer to your question, I'm confident he will like the most part of the team Williams documentary as it covers the era you describe. I bet your dad would also love Weekend of a Champion about F1 legend Jackie Stewart (1970s) and 1: Life on the Limit about the very dangerous years of F1 until modern era, which covers the time period you describe. These, and the already mentioned Senna doc and Rush movie would be suitable.

If your dad struggles reading, maybe photobooks could be an idea. Grand Prix: Fascination Formula 1 and 50 Years of F1 Photography by Rainer Schlegelmilch is amazing and might bring back memories.
