Based only on events up to the end of Voyager, what could happen to all Voyager main characters after the ship got home (also in alternate timelines)?

I know recent Star Trek productions told us what happened with some of the Voyager characters after the ship returned home. However, since there are alternate timelines in Star Trek and because of that, I would like to ask you this.

What can happen to the main Voyager characters after the ship returned home? What career path could they take?
