There are a lot of session types in magento 2 . The ones I know of are listed below ;

1)  \Magento\Catalog\Model\Session //vendor/magento/module-catalog/Model/Session.php

2) \Magento\Newsletter\Model\Session //vendor/magento/module-newsletter/Model/Session.php

3) \Magento\Persistent\Model\Session //vendor/magento/module-persistent/Model/Session.php

4) \Magento\Customer\Model\Session //vendor/magento/module-customer/Model/Session.php

5) \Magento\Backend\Model\Session //vendor/magento/module-backend/Model/Session.php

6) \Magento\Checkout\Model\Session //vendor/magento/module-checkout/Model/Session.php

Can someone please tell me about lifetime, scope and general usage for these sessions, so I can know which session to use when?

Magento 2 provides five types of sessions:

Magento\Backend\Model\Session - This session is used for the Magento backend.

Magento\Catalog\Model\Session - Catalog session is used for the frontend for product filters.

Magento\Checkout\Model\Session - Checkout session is used to store checkout-related information.

Magento\Customer\Model\Session - Customer session is used for customer, frontend login, and all other activities.

Magento\Newsletter\Model\Session - For newsletter data.

Magento\Persistent\Model\Session - Persistent session data is kept in DB - so it’s not deleted in some days and is kept for as much time as we need. DB session keeps customerId + some data from real customer session that we want to sync (e.g. num items in shopping cart).
