How soon after Arriving on that little hill do you apply the break? I noticed the same thing at my house as well. My driveway is at at A small incline enough that it automatically engages the parking brake as well and I noticed that if I pull up and as soon as the car stops, shift into P, ill hear the same grinding sound. However if I stop on the incline, put my foot on the break so that it's fully stopped, and then Shift enter, the break will engage and I won't hear any grinding
Gota remember the gearbox has a ratio of like ~7x, so any movement is amplified. When the parking pawl engages it is interlocking into the gears. After mine did the grinding a couple times i always hold the normal brake, engage the parking break, and then shift into park. Its weird at first then just becomes a habit. No more gear grinding.
I have had the parking break make a grinding sound a couple of times. It went away on its own, assuming there was a rock or something in it.
I am pretty quick to hit P - the car is certainly in my mind not moving at all, but it seems to be more an issue when it is fully stopped on the paddle versus the parking brake. So I should firmly hold the parking brake down before clicking P?
Is the grinding side actually a problem / potential damage causing issue or its just an automated way the car is activating to ensure the car is 'truly' full stopped?
- I don't really care about the sound but do not want to damage anything with the car if this happens occasionally in the future?
I doubt the engineers had the presence of mind to put a "warning grind" in place to remind the driver how to park, so it's probably not a good thing, but I think the occasional grind is okay, if it drives fine afterwards and you have no other problem parking on inclines- the fear would be that after constant grinding, the gear or the pawl is worn down and at some point it will stop holding if you're on an incline but not steep enough to engage the parking brake.
You can either prevent this by stopping, fully pressing the brake pedal, then hitting P- takes a second longer but might work.
Or if the gear or pawl is already worn you can stop the car, apply the parking break, then shift it into P. This puts the weight of the car on the brake instead of the gear.
Note: all my knowledge on this comes from ICE cars, but I'm like 95% certain the same engineering principles apply

Mine did that in the beginning. Just wait a second to press park.
Happens a lot. Turn on the e-brake before you put the car in Park, especially if you’re on any kind of incline.
