Im new to the overlanding idea. Watched lots of videos and read tons of articles. My first big push is a fridge. To support the fridge i was thinking about a single battery setup with a solar charger.
Im looking for ideas for the battery. Im hoping for a battery for ~$250. I dont really want the complexity of DC DC charger right now, if i dont have to.
Ideas?

I was looking at a battery pack like these. I have some golf cart batteries, but 2 would be crazy heavy and they don't seem to be in the nest shape, charge wise.

I did look at this battery a couple days ago in the store.

You need 4 of the first battery to make a 12v system as LiFePo4 batteries are only ~3.2v. Excellent choice for a house battery if you go that route but not ideal for a starter battery so the generally require a battery management system. You'll be out $1500 or more to add a good second LiFePo4 battery to an existing system.

IMO if you can fit a group 31 under hood, get an Odyssey Extreme or whatever Northstar's equivalent is and call it a day (I've heard good things about that second battery you've listed but no direct experience so no comment). A group 31 will more than let you run a couple small scene lights and a fridge overnight and has more than enough capacity for winching or anything else you'd throw at it on the trail.

I love my Odyssey batteries. Have never run Northstar but I want to try them next time I change batteries. Figure out how much your fridge draws and base your panel on that. I have a 50 watt on my Cruiser. It barely keeps up with the fridge while sitting. I have it because my vehicle isn't a daily driver and the normal battery draw kills my battery in two weeks of sitting. The nice thing about my panel/charger is it keeps my battery exactly where it needs to be. driving/camping its enough as ling as I don't sit for more than a day(ish). My trailer has a 120 watt and that's more than enough to keep up with my 50qt fridge.
Most of my trips are desert, mountain trips mean moving my panel around and hoping I get a good charge in my trailer battery.
I don't run a DC-DC converter on anything and I get normal life out of my AGM's. Even before adding my solar.

Maybe that P04 isn’t the right battery for me.
This is a every month camping truck. I think an AGM house battery with a 150 watt solar charger should do what I need. The fridge is suppose to use 19aph over a 10 hour period in the day with the fridge cycling on and off.
