Query: What modifications should I do to my stock LR3 at the current point in its build?

Goal: Be a capable and comfortable go-anywhere (within reason) vehicle for adventures in remote places with my family of five.

Context: I'm currently in the process of doing a thorough refresh of my new-to-me 2006 LR3 V8. I've documented my progress so far in my build thread. In short, I have removed the brakes, the control arms, the steering knuckles and hubs, the air struts, the axles, the sway bars, and the front and rear differentials. This is in preparation for descaling and converting rust on the frame, then painting and sealing with Cosmoline.

I was wondering if there are any mods I should look into doing right now while everything is out. I thought about putting in a front receiver like Purple.helos did. I question how often I would use it, but I'm sure it would be a useful solution in search of a problem. What else am I not considering, but should? I appreciate any advice you all can give me, as I'm new to the platform and off-road adventuring.
