Acknowledged.
But the OP also says " It will be used for all different types of photos" which everyone but me seems to be overlooking.
Ignore the "fast" bit then; after all, most "standard" primes will be around f1.8 anyway.
I just think primes will be compact and light and will avoid knobbing about with zoom. Maybe my suggestions of focal length are not wide enough for some peoples' tastes, but I personally never really got on with 28mm - and again, I kept in mind the "all different types of photos".
