Could one look at the Mensheviks and the Bolsheviks through a similar lens as you do with the Georgists vs the 1910s Progressives? The Mensheviks being more bottom-up (and willing to go slower if needed) and the Bolsheviks being top-down (in order to move faster) but both with the end goal of moving forward with Socialism?
I would not describe Georgism as a socialist movement. Although accomplishing the goals of Georgism would be a step towards socialism, it isn't really aiming to accomplish the same thing. Georgism addresses an issue with land ownership but attempts to reconcile it in a way that is compatible with liberalism. Land owners can still make choices about what they do with their land but pressure is placed on them by the state when it's not being utilized.
Socialism, on the other hand, would not allow for the land owner to exist at all, and the use of the land would be determined collectively by the state.
