Without more info on what you're using the camera for and what is not working the way you expect it's hard to give any good suggestions
The best info you've given is:

I had a photo business. weddings. portraits. sports. during film days. Focus accuracy and exposure are basic necessities
Do you still shoot weddings, portraits, and sports? Are you having trouble with focus accuracy and exposure? In all three scenarios?
I use auto-exposure and have not had any problems with it. Sony sensors keep good shadow detail, so I generally set the camera to underexpose by about 2/3 of a stop to make sure it doesn't blow the highlights; I can always up the exposure a little in post. What camera mode are you using (manual, aperture-priority, shutter-priority, "P" mode, etc.) and what metering mode do you use? Do you only have trouble in certain situations (like back-lighting) or in all cases? Are you using a flash? Does it consistently over- or under-expose? Or is it just inconsistent?
For auto-focus I've found eye-focus to work quite well for portraits. I don't shoot sports, but I expect you would want AF-C with center focus points and try to keep the action in the center of the frame.
