Have a look or ask in the Trek Literature forum. They love
posting reading-order lists over there.
Here's my Voyager post-series reading list:
("Endgame" goes here)
Spirit Walk duology (I skipped Spirit Walk coz I can't stand Chakotay)
(The movie Nemesis goes here)
Before Dishonor (TNG novel where Janeway dies)
Children of the Storm
You might want to read the Destiny trilogy after Before Dishonor and before Full Circle. It's not essential, and Voyager's not in it, but it's the big galaxy-reshaping event that the subsequent Voyager novels are involved in.
