How does BCH manage to propagate such large blocks over the network? And how would such blocks be verified in a limited time?

I know that BCH has an adjustable block cap of max 32 MB. And the network isn’t even operating at even half the capacity. But what would happen if we see blocks filled upto huge sizes like 8-10 mb. How will miners be able to verify such transactions in a limited time? Moreover, if such capacities are observed over a long time and the blockchain size gets bigger, how would a common person be able to run a node?
