The recommendation of «you shouldn’t let your quieter coworkers speak unless they interrupt their way into the conversation in meetings because that will set them up for failure when their future coworkers talk right over them» is a pretty uncharitable and needlessly aggressive attitude toward those quieter coworkers.

Raising one's hand to speak is generally taught in kindergarten and future coworkers will likewise expect that everyone mastered this basic skill. These days there are raise hand buttons in video conference software. When raising hand is not applicable, a quick "excuse me" is not considered a big imposition on either current speaker or person who wishes to speak next.

I used to be too shy to talk on the phone, coming to US from a country where I only had phone conversations with relatives by coming to a communication center at time prearranged via a telegram. I got over that and if someone accommodated me instead, they wouldn't have done me any favors, because things like this are generally expected and accommodations will not always be available.
