Please allow us to pass in an array of objects with a text and value field for the multi-checkbox filter on grids.  So users can see the human readable text field value but it filters on the value field.  You have similar functionality in nearly every other component that needs to show the users a list of data to choose from.

Dynamic grid status content does not announce updates to screen readers during filtering or pagination.
For example, the status message “1 – 4 of 4 items” updates visually but is not announced to assistive technology users.
As a result, screen reader users do not know when filtered or paged results change.

This can be improved to read out how many items are left on the page for the user to navigate them, as in some cases, there might be none.
