I cannot stand park campgrounds...
For me, I boondock in national forests and out west I have BLM lands as an option. Since I use a ground tent and am lazy, I'll normally stay several days at least when I've found a new perfect spot.
In 2020, I spent about 50 days camping in Tennessee and New Mexico. Supply wise, I drop into a town about once a week, resupply and top off water then grab a burger or pizza leaving town. I'll get another month or 3 of camping in later this year.
Camping like this and where I do so is different than going out for a few days. I have a combination of strong, durable gear and simple, reliable gear. You have to be prepared for weather extremes and hiking out if trails get blocked (this happened to me last year) or there's a truck breakdown.
I'm making one change to my gear this year. I'm fed up with propane fuel. At the end of the last camping season, I threw my propane lantern in the trash. Completely fed up with all the fuel used for lighting. I'll go back to white gas. Propane is very good for the stove as a canister lasts several weeks. But for simplicity, I'll switch back to white gas for cooking as well.
I once had a white gas backpack stove valve break while I was adjusting it. It lit my hand on fire causing first and second degree burns.
We were running sort of a figure eight trail so we were close enough to our cars that a friend was able to drive me into town for extra first aid supplies. ( I didn’t have enough for multiple days of treatment.
I called my wife when we got into cell range. Since she wasn’t expecting to hear from me for a week she was a bit concerned. I said “I have good news and bad news. The good news is I get to buy a new camp stove.”
BTW, you can buy a refill attachment at Harbor freight to refill your propane cylinders.
For camp cooking, I’ve tried propane, alcohol, heat tabs, plain old wood, you name it. Best all around is white gas, I think, as long as your fuel bottles don’t leak. I have an old Coleman Peak One that still works great.
I inherited a really old 2-burner Coleman stove, but I need to clean it up and get it working. I remember my dad cooking on that stove when I was little, so it’s at least 60 years old.
For light, there are lots of good LED lights now with long battery life, so I don’t take along a gas lantern. I use the light mostly for reading anyway, and a headlamp for walking around at night if there’s not enough moonlight.
Use the old fashioned kerosine lamps, with the new lamp oils they burn clean and give plenty of light.
I have 8 of them in the house for when the power goes out (as in every winter snow storm, summer lighting storm, or forest fire) and they are plenty of light to cook or read.
I use FEUER model 276, they are light weight, tough, and easy to fill or clean.
I don’t think they are any bigger than your old propane style lights.
