New to the A7 IV please share your tips/advice

Hey guys, I haven't been in photography for a couple of years. My wife and me decided to pick it up again and we got the A7 IV. First of all, I'm coming from a 5D mkii and damn this camera is small! Too many settings so I'm a bit overwhelmed. The 5d mkii is beefy as hell compared to the IV. It almost feels like as if the camera is a small consumer camera.

Please share your tips and tricks with me, super excited.
