Fair enough, but then it shouldn't take too long to get a picture of
what's industry standard. Small signal transistors are SOT-23.
Variations exist mainly in extreme areas, like high current or
frequency.

I have some doubts that you'll get a lot of happiness with QFN packages
on that one, but I'd be interested to hear otherwise.

If you find a cross-reference list of the most common components post it
here! Otherwise it's not traditionally the job of the PCB layout
software, but maybe the $X0k you pay for Altium provides some of this.

Your best bet may be the manufacturers' online selection tables.
