Jamf Connect is just creating a local account. The only magic Jamf Connect is performing is filling in the local account data (username, password, etc.) from IDP information. The rest of the account creation process is more or less the same.
Jamf has stopped supporting login and log out hooks, the functionality is still there but Jamf recommends you don't use them, and they can be very flaky due to changes in macOS. Jamf stopped supporting them about 6 years ago.
Depending on what it is you are wanting to do, a launch daemon is probably the best idea. Recurring check-in one per day/device/whatever may also work, again depending on what you are doing.
