How would you divide the Mario series into different eras?

[Princess Mint]

Most people would do this by console generation, which would be one of the more concrete way to do it. I however feel like there's a strange split in the Wii era between games that feel more in conversation with the Gamecube generation, and games that feel more as foreshadowing of the Wii-U generation. Overall, I don't believe there are actual eras that divide the Mario series, but I'm leaving the question as a sort of artistic exercise because it can still make for a neat discussion. If you had to, how would you sort the Mario games into different eras?

Some examples are: By decade, By release of major entries, By art direction, By the appearance of certain characters like Toadsworth, or just by pure vibes.

By two consoles because every Nintendo console has a sequel, NES to SNES, Gameboy to gameboy advance, N64 to game cube, Wii to Wii U, DS to 3DS and Switch to Switch 2!

Maybe a sort of before, during and after the 3D game craze/2d drought, then Switch as another category? So Mario Bros through Land 2 for pre-3D Craze, 64 to Galaxy 2 for the 3D game era, then NSMB to NSMBU (or whatever the final Mario game released on Wii U was), then Odyssey to present. "Present" could also be marked as Bananza.
