Plus now my window is acting weird.. it's one of those that the window goes down a bit when you open the door and back up when you close it.. except it doesn't go up any more (doesn't even sound like it tries), it just goes down a bit. Open and close the door a few time and the window is half open :/
I can roll it up fine with the switch while in the car. Hopefully something that will reset itself when the car can start with the window fully closed and not some sensor or expensive electronics part.

I know you got this working already, but I wanted to add a bit about this.
Vehicles since the mid-2000s started adding far more sophistication and complexity with things like Body Control Modules (BCM); everything that was previously just a dumb switch (like your windows, seats controls, locks, lights, etc.) started reporting its telemetry through a centralized BCM, from position/status to voltage and so on. It has made troubleshooting problems with these functions much easier as you can read the data stream directly from the BCM if you have a capable diagnostic tool. I myself run a ThinkDiag and a JLR Mongoose Pro cable with SDD software.
The drawback is that everything functioning correctly is much more dependent on the battery having enough voltage, otherwise the vehicle will (usually) prioritize the ignition circuit over keeping all these other systems energized, and having a weak battery will absolutely cause all sorts of weirdness for windows, seat position controls, etc. The window position issue is a really common one where a weak battery condition is concerned. Sometimes you'll have to perform a complete relearn for the window switch, which is usually pressing and holding the window switch in a certain position for X seconds, then pressing the other direction. Seats have the same issue sometimes, you have to move the seat all the way to the forward extreme (don't do this while sitting in them!), then all the way back before you can get the full range of movement out of them.
TL,DR: Replace your battery every 5 years, possibly earlier, or you'll get weird sh-t happening with the electric functions in your vehicle.
Some vehicles are really easy to swap the battery, others require a two-way diagnostic computer to 'code' the vehicle to the battery as the vehicle will adapt the alternator charging logic to how new/old the battery is.
