What search criteria to use for a "get current" change package?

We are starting our first "get current" project for PS HCM 9.2, having upgraded last year and brought up to PI 23.  Since then we have applied all tax updates a few other patches.

When defining the change package, what search criteria do most people use for "get current'?  What is the difference between "All Unapplied Updates for Installed Products" and "All Updates Not Applied"?  (and what is it looking for to determine "installed products"?)  The resulting change packages seem pretty similar to us even though we have products we don't use like Absence Management and Global Payroll.

We tried both options, and are getting a lot of bugs/objects for Global Payroll, for example, even though we don't use GP we use Payroll for NA.  Is this a typical experience and is it best practice to install all updates regardless of whether we use the product?
