I understand that you cannot use a RAW image in Lightroom without a profile. I get that. I was looking for a starting point whereby I can see with pretty good accuracy what my camera's sensor is recording without moving any sliders!
You can't do that in LR. Or many raw converters. You can't do this without settings, zero is a setting.
First of all, this is what raw looks like with one type of previewing raw data:
You probably don't want to view your raws this way but none the less, the above is what raw looks like with very minimal rendering from what is just a big pile of numbers.
Next, you probably want
scene referred output based on what you say you want

So we're back to your original question about profiles and presets and turning everything OFF. It's not possible. As such, any setting you start with that you are happy with as a starting point if fair game. If that means using Adobe Neutral, so be it and fine.
What you'd start off with using a custom profile could be an interesting area for you to investigate but let's go no farther down that path unless you so desire.
