Will your flash be the main light or a fill light?

Disregard them for your purpose

Then you will have to meter the ambient light and choose a
shutter/aperture combination that will under expose it while giving
correct exposure for the flash. Not always easy to do with focal plane
shutters.

meter ambient light, select an f/stop that can give you enough flash
exposure and enough ambient light.

remember:

flash is controlled by the f/stop and output power
ambient is controlled by the f/stop and shutter speed.

your flash sync speed (for focal plane shutters) is the maximum speed that
will allow the flash to fire while the shutter is open fully from one side
to the other, you can usually shoot at slower speeds and many cameras have
choice of first or second curtain flash (so the streaks can look like they
are following the subject and not streaking through them)

so you could select a large f/stop or low output from your flash and then
look at your meter and select a shutter speed that will allow the ambient to
build up.

if your flash is the key light then you want your background to be one stop
under, maybe 1.5 stops

if your flash is fill then select an f/stop or output power that will be one
stop under the ambient exposure on the subject.
