You should never exceed any of Ford's weight limits if you want to stay safe. There are a bunch of different weight limits, but the three you need to worry about are GVWR, GCWR, and receiver weight ratings. If you don't exceed any of those three, then you won't exceed any of the others, such as tire ratings, wheel ratings, axle ratings (front and rear GAWR), etc.
There are three limiters to the amount of weight you can safely tow. Gross vehicle weight rating (GVWR) of the tow vehicle, and hitch receiver weight ratings you posted above are two of them.
You're missing two other pieces of info - the GCWR (gross combined weight rating) of your van, and you also need to know the rear axle ratio of your van so you can determine the GCWR by looking it up in your Owner's Guide.
You need to understand the meaning of the alphabet soup terms GVWR and GCWR.
The gross combined weight rating (GCWR) is the maximum total weight of the wet and loaded van and trailer combined. So it may be the limiter of how much trailer you can tow. The GCWR should be in your Owner's Guide, but you'll need the axle ratio to determine what it is. If the ratio is 3.73, then your GCWR is 15,000 pounds. If the ratio is 4.10, then your GCWR is 18,500.
The gross vehicle weight rating (GVWR) is the maximum weight that can be on the 4 van tires at the same time.
With the GVWR, GCWR, and receiver ratings, you can easily determine the max weight of any trailer you can tow without exceeding any of Ford's weight limits.
To do that, load the van with everything you'll have in it when towing - driver, passenger(s), pet(s), luggage, tools, extra fluids, cooler full of cool, and any other cargo you might haul in the van. Then go to a truckstop that has a certified automated truck (CAT) scale, fill up with gas, and weigh the wet and loaded van. Most truckstops charge around $7 to $10 to weigh your rig and print out a scale ticket for you.
Subtract the weight of the wet and loaded van from the GCWR and that gives you the limiter of max trailer weight you can tow without exceeding the GCWR of the tow vehicle.
Subtract the weight of the wet and loaded van from the GVWR of the van, and that gives you the max hitch weight you can have without exceeding the GVWR of the tow vehicle. A properly-loaded "bumper pull" RV trailer will have hitch weight of 10 to 12 percent of the gross trailer weight. To err on the side of safety, assume 12 percent. So divide the max hitch weight by 12 percent to get the max trailer weight you can have without exceeding the GVWR of the tow vehicle.
The max tongue (hitch) weight limit of your receiver is another limiter. Your max hitch weight limit of your receiver (with a weight-distributing hitch) is 1,000 pounds, so with 12 percent hitch weight, the max trailer weight you can tow without busting that limit is 8,333 pounds.
Assumption: Your wet and loaded van weighs 8,500 pounds per the CAT scale, and you have the 4.10 axle ratio that results in GCWR of 18,500 pounds.
18,500 GCWR minus 8,500 leaves 10,000 pounds for max trailer weight.
9,300 GVWR minus 8,500 leaves 800 pounds for max hitch weight. 800 divided by 0.12 = 6,667 pounds for max trailer weight.
Because your receiver is limited to 1,000 pounds hitch weight, but the GVWR limits your hitch weight to 800 pounds, then the receiver is not a limiter.
So what do we have? If your wet and loaded van weighs 8,500 pounds and you have a 4.10 axle ratio, then your limiter is the GVWR of the van. So the max weight of any wet and loaded trailer you tie onto should not exceed 6,667 pounds
Of course, changes to the max weight of the wet and loaded van will change those numbers. Remove most of the seats, and limit the number of passengers you haul while towing, and the max trailer weight goes up dramatically. Your van can haul 15 passengers or tow up to 10,000 pounds trailer weight, but not both at the same time
So if the max weight of any trailer you can tow is 6,667 pounds, then look for a trailer with a GVWR of less than 6,667.
And then there are the "extra" towing stuff, stabalizers and whatnots.
The big extra is the hitch. Not the receiver you already have, but the rest of the hitch between the receiver on the van and the tongue on the trailer. There are three ways to go.
One way is with a simple drawbar with a ball. That is called a weight-carrying (WC) hitch. That's fine for trailers that gross less than 5,000 pounds and have minimum frontal area, such as a utility trailer. Both the drawbar (ball mount) and the ball must be rated for at least as much weight as the max weight of the trailer.
Next up in cost is an ordinary weight-distributing (WD) hitch, rated for the max hitch weight of your trailer. Those cost around $500 to $800 with the needed sway control. They are made by Reese, Draw-Tite, Curt, Equal-I-Zer, and others. That is the minimum hitch you need for a travel trailer (TT).
The top of the line in hitches is the Hensley Arrow or ProPride. They cost about three times as much as the ordinary WD hitches. If you want maximum safety, then that's what you want. If I were planning to drag a TT, then I'd insist on a ProPride hitch.

As to other items you might need, probably nothing. Maybe a rear anti-sway bar, and maybe airbags in the rear suspension. I wouldn't worry about either until after your first towing trip. If the van tends to lean way over on sharp curves, and your van doesn't already have them, then maybe add anti-sway bars. The most popular is Helwig.

After you have properly
adjusted your WD hitch, if your headlights still aim at the stars and blind oncoming drivers while towing, then you need airbags to compensate for the hitch weight and raise the rear end of the van back up to level. The most popular are Firestone RideRite.
