Malmslättsvägen is now marked with cycleway=lane, but this doesn't
show on the map here. And how can I indicate that this bus stop
is only on the southern side of the street (buses going east)?

Its perhaps not ideal to place the bus_stop off to the side of the
highway since the stop is part of the highway.
What's more, the bus stop is a physical area, some 5-6 metres wide
that is a wedge between the street and the cycleway+sidewalk.
I'd like things to be

Yes, they are probably using the same scale bar for WGS84 and Mercator.
As far as I know, in WGS84, the scale bar is correct vertically (lat), but in
Mercator, that scale bar is wrong both vertically and horizontally if you are
far away from the Equator.
As you say, one easy way would be to

Hi,
In Mercator distance is constant independent of orientation, isn't it?
No, the effect is just not as pronounced as it is if you use EPSG4326.

Wrong. Quoting Wikipedia:
While the direction and shapes are accurate on a Mercator projection, it
distorts the size.

Wrong. Quoting Wikipedia:

In other words, the Mercator projection is conformal, but not equidistant.

Not true. The very idea of (the transversal) Mercator is that
