[Under extrusion after every layer change]

disabling coasting also seems to work for me, or at least reducing the standard m³

[Bridging - start above a wall?]

I've had similar problems, my bridges stop before reaching the walls in cura. I've tried tweaking all overlaps and coasting settings etc, but can't seem to fix this. Would be nice to have a "start bridge on wall" setting, adjustable to the amount of wall or just a good overlap setting for bridges specifically.
