If you only have one short layover in the Schengen area per journey, you can generally transit without visa. In your case, it will be possible both in Paris and Munich. Filipino citizens don't need visas for airside transit in most Schengen countries, even without US green card. For some reason, the only Schengen country applying restrictions for airside transit is Hungary but in that case the US green card would still exempt you from the airport transit visa requirement, so you are fine in any case.
See Do I need a visa to transit (or layover) in the Schengen area? for a full explanation of the rules.
