Switching font families in Word while preserving optical sizes

New poster here, with a newbie question. I'm using Word (on Mac) to lay out a CV, and am using various variants of Arno Pro (Semibold Subhead, Regular, Caption). Then I decide to see what it'd look like in Brioso Pro; select all, go to the font menu, pick Brioso Pro ... and all the work in picking optical sizes is obliterated: everything is in Brioso Pro Caption. Is there a fix for this? Or do other word processing programs (as opposed to InDesign) have the capability I'm missing?
