Default Selecting I/O pins

Hi,
I was recently asked in an interview that what points you will
consider while selecting the I/O pins in FPGA ?

One thing which came to my mind was :
1) considering board aspect that the pins corresponding to peripherals
should near to that peripheral so as to minimize the routing delay
in PCB.

2) pin should be compatible to the I/O type of peripheral device, i.e.
LV_TTL, LC_CMOS etc.

Were my points valid ?
Any other points are welcome.

Regards
