2004 Subaru Forester Water damage

Got stuck in 1.5ft. Right side took in about 4 inches of water over the course of 10 minutes. I don't think I touched the computer because the car was on a hill tilting backwards. Everything electrical works except something in the ignition (lights, windows, windshield wipers, radio, air, etc.) The car won't turn over, engine doesn't even try to start. There was no water in oil, yet moister in the intake. I was told to blow the spark plugs with air and did that. There is no remaining water except in the rear right floor. Water got into engine bay, there was no skip plate.
We tried to 2nd gear start, when started to let out clutch the car almost came to a stop. (I've done multiple 2nd gear starts successfully, this one was different like I was putting on the breaks when I let the clutch out. The second try I eased into it and then fully drop the clutch. It made a super bad noise, like I messed a gear up or something. We went straight home after that cause I thought I broke something more. Also tried to jump battery and change battery to see if the ild one didn't have enough juice. But it didn't change a thing.

I have video of trying to start car and sitting in puddle.
