In upgrading our electrical we have the choice of either keeping the
main breaker inside the house or locating it outside as part of a
combo unit with the meter?
[Note we need a separate main breaker since the main panel is about 20
feet away from where the meter is and the supply enters the house]

The main breaker needs to be within 10' of where the power comes in.

Are there any disadvantages (or advantages) to having the main breaker
outside?

It meets code in your case? Get one that is lockable, if you live in an
area with pranksters.

(note we still will be able to shut off power inside at the main
panel, I assume)

Any panel with more than 4 or 6 circuits, needs its own "main" that
shuts that whole panel down as well as the "house main".
