How many products do you know?

I work with one of the big 4 and constantly get pinged for Sailpoint , Okta .
To be fair , I know Entra, Saviynt, Cyberark (Pam) , OIM, ping CIAM , CA IdM as well but nobody uses it..

How many tools do you need to know to be a Successful architect today ? Expectation are being keyboard hands on for all tools but it’s not feasible to learn it all.

Any suggestions? I’m 10 years in IAM now
