I find that the problem with 0 ohm R and such like is that they are a fixed width, I also find it rather awkward to add them to a board, then to the sch and so on. I also prefer to have a sch. to work with.
What I do for single sided boards is set the via size to the same as what I use for a normal through hole component Then I just route the board as normaly on the copper side, and where needed I switch to the component side and run tracks as if they were my jumper wires. The component side copper print becomes my jumper layout (if it ever gets that complex) For small home projects this works very nicely for me.
