I recall also seeing a jack "Pad" that had a channel on it with a threaded rod, a nut welded on the end of the rod (or a bolt head)
The jack fit into the channel and had a nut on the end of it which also fit over the rod
By turning the rod you could move the hitch a few inches left or right. Made it possible to do the lateral line up. Never needed it on my under a ton trailers. (Still don't) so never bought one.. Camping world had them way back when IIRC.
One thing they have today is called, again if I recall .. Well I checked and I don't recall correctly so I won't give you a wrong name...
But it's a pair of rods, magnets on one end, a couple of bends in them.. One "sticks" to the trailer, one to the tow vehicle, and when the rods touch... Lower the toung jack, latch the hitch, hook up the chains and cables, and stow the aids, and away you go.
One other option you might consider.....
You can mount a back up camera in a license plate frame (or for that matter a license plate BOLT) now days
