If your board is really old, it may even be an older package, a round metal can similar to the TO39.
The CA3130 was externally compensated, because at the time it was designed, the typical slew rate for internally compensated opamps was very slow. Only between 0.5 to 2.0 V/us.
Newer opamps have far larger bandwidths, so you can safely clip out that capacitor.
The real question is: do you require the strobe function?
I'm very sorry for the delay, I completely forgot to come back here and had other projects on my mind.
To answer your questions, the package I use is a SOIC. Here is the exact model: https://uk.farnell.com/1018162. Also I don't need a specific package as I can just redo the PCB if needed.
It is actually a new PCB: I am designing it right now. I would like to use a battery as a power supply and it would be more convenient to have <5V as an input.
Concerning the strobe function, the only thing I do is to link the pin 8 (strobe) to the 1 (offset) with a 1nF capacitor because I read that it's better for the stability of the op-amp. (I think it's the external compensation you refer to)
A high-bandwidth OP is difficult to handle. It's likely to fall into parasitic oscillations if not properly bypassed. It probably never works stable on a breadboard. It has higher quiescent current than necessary.
There are so many low voltage general purpose OPs with 1 - 10 MHz bandwidth.

My math tells that the maximum slew rate of a 2 mV 60 Hz sine is about 0.75 V/s. But slew rate is measured for the OP output, so required slew rate depends on which output is generated by the 2 mV signal.
