Is it possible that the shortestpath + fuse displaying clean edges does not show that I have several overlapping edges, and when I resample, they become visible?

This is exactly what causes both of your issues

Shortest path is likely to produce overlapping paths especially because many paths end up travelling through the same edges before eventually diverging

Fuse just fuses the points but the amount of curves will not change so the overlapping segments prevail

Resample even without resampling likely makes points unique per curve to be able to store curveu since if points are shared among multiple curves then a single point would have to store multiple different curveu values

So to clean up your geo you can append Convert Line SOP + Poly Path SOP after your Fuse
That will make sure each path is a single curve at least up to the branching point

Then Resampling to should behave better
But instead of using Resample to also compute curveu, I'd recommend Edge Transport, to get some real distance attribute for curve network rather than notmalized curveu per curve as those will be just segments between branching points

1. I'm not sure you can use wildcard for the Output paths, at least for me it always returns nothing, so try to be specific in what you are grabbing

2. not sure if this would be the same for all rigs but in Electra you can get controls by invoking /electra.char/Base.rig/drawable_output -> geo

You can also just adjust the Input Timestep parameter on Retime SOP

Change it to something like
