Before Meteor, A Realm Reborn Soundtrack, Heavensward Soundtrack, Stormblood Soundtrack, Shadowbringers Soundtrack, Endwalker Soundtrack (coming soon) are the ones you want.
I think there is another one between ARR and Heavensward but I can't remember. If you buy those specific albums, they only contain game music, with a few Before Meteor tracks being part of some of the later ones since they eventually started repurposing 1.0 music in other expansions.
