From RS Italy 2018, p. 61:
For most people, the best choice is the Museum Pass, which covers entry into the Doge’s Palace, Correr Museum, and more. Note that seven of the most visit-worthy sights in town (the Accademia, Peggy Guggenheim Collection, Scuola San Rocco, Campanile, and the three sights within St. Mark’s Basilica that charge admission) are not covered by any pass.
For the sights you've listed so far, the Doge's Palace and Correr Museum are covered by the €20 Combo Ticket, St Marks Basillca is free, and the museums inside the Basilica are cheap and you just pay on the spot. If you want to see at least one more museum that's under the €24 Museum Pass, then that pass is worthwhile.
The Chorus Pass for €12 covers most admission-charging churches, including the Frari (again not needed for St. Mark's).
I would also get a 48-hour vaporetto pass for 30 euros per person. You may be better walkers than I am but your hotel location is not the closest to most sightseeing, so you might like to take a couple of boat rides per day.
