2015 Nissan Altima No Start

Sorry if this is a long read. Just trying to be thorough.

TLDR: Battery died and now the car will not start after recharging.

History:
I inherited a 2015 Nissan Altima 2.5 S with the 4 cyl engine. It has around 55K miles. Responsibly driven. Most mileage is highway miles. Car has no history of mechanical issues. It does have a parasitic draw somewhere. Never found where because with normal use, it was never an issue. Battery did need replaced so replaced with fresh, new battery.

I parked the car in the garage and only started it roughly once a week. Did this for a while because it was not my daily driver. Life was fine. I got a job that I had to travel for so it sat in the garage until the battery died unfortunately.

Problem:
Car has no crank, no start. Recharged the battery and it holds a 12v charge. Replaced both key fobs with fresh new batteries. Confirmed power is getting to the starter and alternator. I have checked every fuse and relay under the hood and all seem fine. Even checked the fuse box ports to make sure they are getting power and still checks fine. Also checked the fuse panel attached to the hot post of the battery.

No power is getting into the cab. No dome light, radio, headlights, brake lights, etc. No power is getting to the fuse box under driver side dash. I also checked these fuses and relays.

It is like power is not getting through the firewall. I’m not a mechanic by any means so any input is appreciated. Im out of ideas of what to do next outside of having it towed to a mechanic, which I would prefer not to do if possible.
