While in general the presence of the giant planets reduces the relative habitability compared to a system with just an exo-Earth, there are some cases where the giant planets make the system "ultra-habitable":

For each giant planet pair, we consider 80 different locations of the exo-Earth. At each of these locations, we find the stability and habitability probabilities. Then we can integrate over the exo-Earth locations to find a relative habitability for the giant planet pair.

In general, as the exo-Earth's eccentricity increases, it gets more sunlight from its star, making it less habitable in the inner regions and more habitable in the outer regions.

Of course, just hours after I made the video for this week, the sneaky Webb team announced that in fact the alignment phase is DONE! And they released these cool snapshots from all 4 #JWST instruments. Yay!!
