Check it out! Started with a MagBak wireless charging pad. Pricey, but it's the only one I could find that had magnets strong enough to hold a significant amount of weight, meaning it will hang on for the ride.
Attached it to the blank trim piece behind the armrest. Got a flat USB C to USB C cable (right angle on one side) and a 12V USB C flush power adapter. Put the wire through the back of the armrest.
Got a generic MagSafe magnet to stick on the back of my phone case and presto! Phone secured and wirelessly charging!
Placing the phone on the pad to get is charging is a little finicky, and you could definitely get a longer cable and put the charger up higher so you can place the phone on it in portrait (I just didn't want that much cable to show at the bottom) but it's been working great so far. Phone doesn't move or stop charging even on bumpy roads.
The 12v outlet supplies a lot more power than the USB ports and the charger has a built-in fan so your phone is much less likely to overheat when using Android Auto (which I have hooked up wirelessly using the AA Wireless 2 adapter tucked away in the armrest).
Who needs crappy OEM wireless charging pads that are badly placed, cook your phone, and barely charge it!
