Is it possible to get Format() to pad with leading zeros rather than spaces,

interprets e.g. %02s as being padded with zeros.
For string arguments, this is not possible.
You can use %.2d for this, or %.2x for hex numbers:
araminta: >./tf
000F
araminta: >cat tf.pp
uses sysutils;
begin
writeln(format('%.4x',[15]));
end.
In a similar vein, am I correct in understanding that FPC's Format() doesn't
allow the case to be controlled in hex output? C's printf() distinguishes
between %x and %X for case control.
You are correct in your understanding.
Michael.
