I've towed an 01 Jeep Cherokee, three different Grand Cherokees and now a 2019 Cherokee Limited with the Ready Brute Elite tow bar with surge braking. My new Cherokee has the optional 2.0 turbocharged engine, which is worlds different from the 01 Cherokee with the straight six. The old six would get about 12.5 mpg in normal city driving. The new 2.0T, with way more power and torque is showing 27.5 so far on an engine that's just breaking in. The EPA rating is only about 20 mpg. To be towable, this model requires the Active Drive II transfer case with neutral.
Depending on your needs, towing capacity and budget, something like the new Cherokee is very comfy, has 4WD and decent room. Several smaller FWD cars and others are flat towable. A lot of cars with manual transmissions are towable. Just make sure the car you want will work. For example, I bought a 2014 Fiesta ST thinking that all Fiestas were towable. It turned out that the ST model with the six speed manual wasn't towable.
