If you don’t want rear brackets/sockets, you can often do custom width side supports. (As you can probably guess, these can be fiddly to get right.)
Failing that (drawers in the middle of a wide cabinet, etc), you can create solid struts (1x2 would work) that the rear socket can attach solidly to. Horizontal is probably easier, though you could do upright, which would carry weight without relying on the strength of fasteners.
All that said, rear sockets into thin back panels as you’ve described seem janky, but for light loads, they seem to work.

Rockler Drawer Installation Brackets
The usual method of installing side-mount slides onto a drawer box involves a lot of measuring, marking and room for error. With the Rockler Drawer Installation Brackets, the process is much simpler and more intuitive. Just clamp the brackets in place wherever your drawer needs to be, set the drawer onto the brackets, pull out the slides and drive your screws. Since you can visually see the location of your drawer and whether or not it's level, you're less likely to make a mistake. Each bracket has a shoulder that rests on a rail or the cabinet bottom, providing a positive reference stop. Alte
