I’m using a Sony A6400 with a Sony 90mm macro lens.
I shoot in apature priority and have found f11 to yield the best results.
ISO is on auto but usually comes in around 5000
shutter speed is auto and usually comes in around 1/160
I use manual focus from time to time, most of my shots are done in auto focus.
Post processing is limited to cropping and increasing sharpness.
