Topband: how to hear through static crashes?

For me - Receiver AGC doesn't matter - typically on fast.  However, I will
back the RF gain back so that most of the static crashes do not activate
the AGC.  I will advance the AF gain to compensate.  I find that setting
things up this way allows my brain to focus on the signal without the
signal changing amplitude due to the AGC being triggered by a static crash.

I am not sure IF bandwidth matter that much at this point - but typically
use 400 Hz.  I also find a CW tone down around 400 Hz works well for me.

Not sure any digital processing really helps with this - I haven't ever
found something that I would say really works.  Diversity seems to help -
but only after you are using directive antennas to minimize the static if
possible.

I have done this for a very long time - from using an S line on 80 meters
at K6RR, to a C line on 160 meters at P40V, a TS850 and K3 here at my
station.
