It's like anything else -- you choose a brand based on reputation, price, features and availability. For instance, I would have rather purchased a Wells Cargo trailer, all things being equal, because they have the best reputation among cargo trailer people. But they are more expensive than most, and I was friends with a Pace-American dealer, so I bought a Pace-American. Other well-known brands include Interstate, Haulmark, CargoMate and Featherlite. And that's not to say that other brands and, frankly, no-name brands aren't equally as good. Trailers can be primarily steel-based, which are heavier, or primarily constructed of aluminum (Featherlite), which is lighter but much more expensive.
Within a brand, there's usually economy, standard and commercial-level build qualities. Economy trailers (P-A's Outback, Wells Cargo's TC Trecker, Haulmark's Light Cargo) usually have minimal features, flat roofs and light-duty components. The standard trailers (P-A's Journey model, Wells Cargo's Road Force, Haulmark's Transport) have upgrades like sturdier, rounded-top roofs and roof caps, better suspensions (torsion is usually better than spring axles, for instance.), thicker walls and floors, LED lights and upgraded tongue jacks. And of course the upper end trailers (P-A's CargoSport, Wells Cargo brand, Haulmark's Cub, Kodiak and Grizzly trailers) have more toys and goodies, plus more available options.
If you are ordering a cargo trailer to be used for both camping and cargo, some of the more useful factory-built options might be windows, insulation, RV-style side doors and electricity (AC ad DC). A 5'x8' and 5'x10' trailer may or may not have a side door standard; it can usually be added as an option. The 6' wide trailers usually come with a side door. Depending on your needs and wishes a pull-down ramp door in the back my be more useful than the standard swing-open rear doors.
5' wide trailers may pull easier because of their narrower profile on smaller or lighter tow vehicles (TV) like your Jeep. A 6' wide trailer has the big advantage that most people can sleep across the width of the trailer, which allows for more floor plan options. You also have to think about where you're going to keep the trailer when not using it -- my HOA has covenants preventing me from keeping it in my backyard or driveway, and it's moderately expensive around my area (Maryland) to store it in a facility ($100/month), so I had my custom trailer lowered a foot so it would fit in my garage. All other things being equal, and considering the ultimate weight of your built-out trailer, I don't think anyone ever regrets getting the biggest trailer they can afford. For instance, mine is a 6'x10', but I still sometimes question whether I would have been happier with the 6'x12' -- two extra feet can make a great difference at times.
Just looking at the albums and posting of the other people here, you'll see many other options and ways that people have worked around difficulties with existing trailers. For instance, insulating the trailer is pretty important to keep the inside cool in the summer and warm in the winter. If you can order a trailer with insulation, great! If not, or if you are acquiring a second-hand trailer, it doesn't take a lot of work to remove the interior walls and add your own foam insulation from Home Depot or Lowes.
That should be enough to get you going, but don't be afraid to ask more questions.
