Are there particular pages in the wizard you think look bad ?
I actually thought it is better with the larger size. With the smaller
min size, every time you press the back/forward button the window jumps
around in size. This is painful because if you press "back" once, the
window shrinks so your mouse is now above "cancel", making it pretty
unpleasant to use. The larger size hasn't entirely solved this, as it
still jumps a bit in height if certain expandable sections are expanded
but there's much less jumping in general.

For the popover vs the combo box, it allows more flexible UI design. The
popover lets you control size of the list, and include extra widgets such
as the search hint & the filter checkboxes.
The popover is easier to manage that the popup window, because Gtk
will automatically figure out the best position to place the popup
at relative to the widget we designate the owner.
