Usually even the manufacturer of the switch only guarantees functionality with a subset of SFP modules. The safest bet is to look for the manufacturer qualified device list and choose the cheapest module, that still satisfies your requirements. Maximum length of fibre cable and throughput will be the deciding factors.
Note that, unless your cable is many kilometers long, you do not need an 1GB SFP. 1GB can be easily transfered via twisted pair ethernet.
You probably want a 10G, short range (<1km) SFP module.
Once you have found one, buy an identical one for the other side, don't mix.
