Hello Surendra
In the following documentation, you will find the recommended configuration procedure for Bridge Domains. In it, you will find several application scenarios and the resulting settings for ARP flooding and other parameters as well.
https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/1-x/ACI_Best_Practices/b_ACI_Best_Practices/b_ACI_Best_Practices_chapter_010.html#id_26514
This document also includes a detailed explanation of what the ARP flooding parameter does and how it actually works. This should give a well-rounded view of what should be done in most cases.
I hope this has been helpful!
