Agree. Getting these under your fingers really helps my fingers. With the lockdown, it presented time for more Bach. Last January I wanted to work on Bachs French suite 5 and now finishing it up at speed.
If I listen to some beautiful classical piano music, why not learn it?
Classical helps other chops and your reading. So much piano music out there. Remember, the physical side of things. Being in my 60s, keeping the hands and mind in shape playing classical or other stuff to me is obvious.
As for gigs, solo or otherwise, that's another can of worms that fluctuates. If more time is available, you can still improve obviously. Playing in public, you may never make everyone happy no matter how you play.
Personnel standard matters more to me.
