If the motor on the electric tongue jack on your 2017 Forest River Flagstaff Super Lite tandem-axle travel trailer operates but the jack does not raise or lower the trailer tongue then you might have over-extended the jack and damaged the internal screw mechanism. You might try the manual crank handle to see if the jack extends or retracts when manually operated. If not, then your jack needs to be rebuilt or replaced.

Some jacks like the Stromberg Carlson # SC63VR have a built-in auto-stop feature that prevents damage to the gears from over-extension. This jack has 4500 pounds of lifting capacity

Any weight-bearing item - a jack or a winch - will work better and last longer if operated below its maximum rated capacity. If you do prefer a new jack instead of repairing your original unit then the Husky would be an excellent choice.

Since you have a wheelbase/axle spacing of 38 inches the correct hanger kit for slipper springs would be the part #HAP-105-205-01. And then for a 7k trailer axle the u-bolt kit you'd want would be the part #APUBR-8. I attached the diagram to use…

The length of wire desired depends on your vehicle connection and your personal preference. You want enough slack for turning, but not so much for dragging as you mentioned. A little extra slack isn't a problem and not enough could lead to stress…
