I’m building a forward‑facing camera setup to mount on a machine, enabling me to see what’s ahead while operating it. The entire system—display, camera, Raspberry Pi, and step‑down converter—will run off a 12 V DC battery. I’m planning to use the 7″ Raspberry Pi touchscreen display. Could someone help me choose the right Raspberry Pi board, camera module, and 12 V step‑down converter for this setup?
Based on your scant description, I’ll start off by saying let’s skip the Pi and stepdown convertor and simply use an off the shelf camera system that’s natively 12 volts. For a few more dollars, go wireless.

For sake of ease I second Brow’s recommendation. While you can certainly do the same DIY, it can be a bit fiddly and usually requires more user intervention
The ready made solution is also cheaper and probably works less than a second after turning it on.
If you must use a pi, a pi zero along with a camera and the 7" touch screen plus a 5 volt buck converter like the one below will do.
