Is there a convention for which way joists run in a house? *e.g. Front to
back or side to side?

And if the joists in the loft run front to back, would all the others?

Commonly front to back downstairs, with sleeper walls to support the
joists and
reduce the span.
Often across the house on the first floor, using internal walls to
reduce the span.
And in the loft whatever direction is needed to tie the rafters,
usually parallel
to the gables.
Basically a compromise between shortest span and function.
