The cable will land in Cape Town, a coastal population centre.

Johannesburg is the largest business and population centre, but it's far inland. Cape Town, though it is further south, will have a smaller ping time to US and Europe.

How good/reliable are the Johannesburg to Cape Town connections? I'd assume they're as good or better than the oceanics leaving.

Sure, but it's 1200 km / 780 miles straight line from CT to JHB.
