@Xeviat I'm not sure if this is what you're looking for, but I always took lore as more of a recommendation than the lore being married to the mechanics.
For example, I once had a ancestral barbarian gnome. But his class abilities were flavored more like an Artificer. His unarmored movement was based on him having rocket skates, reckless attack was from having rockets attached to his elbows, his AC came from having a gadget that provided an inertial multiplier field around his body, his rage was an alchemical injection like Bane from Batman, his danger sense came from having an AI that would alert him to danger, and his ancestral guardians were trapped in a containment unit on his back like from Ghostbusters. It was really fun coming up with inventions to explain the barbarian.
I actually don't really like refluffing classes to that degree. To me, classes are a real thing in the setting, not just a collection of mechanical abilities that can be reflavored. But, many people do this, and I'm glad it works for them! And you and your group!
