Is the Sock/Berrettini way the right way to coach juniors going forward?

With kids becoming increasingly time poor as schools get more demanding (post COVID this is), is the Sock or Berretini school of tennis of having a good serve, dictating points with forehand and finishing off at net the way to go? Both Sock and Berrettini are noted for being two of the only top pros in recent memory to finish their schooling in person rather than online, so it's obvious such a style takes far less time on the court to refine, which could appeal to kids or parents who wish their kids to finish school?

I’d model their games after Tsitsipas. A comfortable all court player with a solid forehand. But maybe not teach the one hander anymore.

I feel like the backhand is receiving less focus in terms of coaching and training of next gen players. Many players (eg. lots of Americans) have big serves and forehands, but mediocre backhands. I believe the ultimate player should have a decent backhand and forehand like Nishikori, Goffin, etc.
