For now I did just buy an external dashcam battery pack. Ran the wires on top of the headboard and down the B pillar then onto the door underside of the front passenger seat.

I don't think anyone suggested cutting anything. I've hardwired stuff in 3 WK2's and no dealer will be able to detect anything. And if you did cut something and didn't do something really stupid, a dealer probably wouldn't even care if they did notice.
There is plenty of paths to get to Switch or UnSwitched power either through the Front of Cigarette Lighter Adapter or the Back. I prefer the Back because a DEALER doing service will see it and might baulk. If you do it neatly, properly and professionally they probably won't notice or care. The WK2 is very modular and very easy to get to places.
Using the 120V outlet for 12V (or 5V) Dashcam will look like a HACK and will immediately raise a red flag with a lot of Service Techs. Even if that looks like it's easily disabled they will wonder what other HACKS were done.
You will waste more battery going from 12V to 120V back to 5V. I believe most, if not all DashCams are 12V. And you can probably run then 24/7 with a "Good" battery. Some have motion sensors, timers, or battery monitors to cut down on changes of depleting the battery. They also make separate devices that will cut power n hours after shutdown. Which will cover most conditions you might want a camera to cover. There is already stuff on 24/7 in the jeep. Adding a typical small load of a dash cam probably won't hurt. Lots of folks run dash cams 24/7. But if you want it switched, then just power it by a switched circuit. And don't even think about using the 120V AC to DC inverter for this.
Here is thread to get switched 12V. No cutting. Also there is an easy path up to the mirror area.
You can also tap the mirror for switch 12V. But that's a little tricky. I did once and didn't like doing it. I needed to run wires down anyway so it didn't make sense to tap power from the mirror.
