Is there any surprises in using high bandwidth instrumentation amplifier
If you are really pushing the bandwidth then the parasitic capacitance of the jumpers and "spare" gain setting resistors will cause a peak in the frequency response at low gains that may not be acceptable. See figure 21 in the data sheet for the basic clues at low gain with what would be a simple small resistor across RG terminals. You are significantly extending this with the jumpers and "spare" resistors.

As pointed out in a comment, you need to tie the measurement terminals loosely to ground - see "input bias current return path" on pg 22 of DS. This may cause a common mode noise problem if the resistance for leaking the current is too high and you are at high gain.

Be also aware of the input range especially when the supply voltage is low. You have a negative supply of 9 V and this means the voltage range of the inputs can go as low as -6.7 volts before hitting problems. It's less problematic on positive voltages.

Make sure you use high stability re
