Would be great to have a config option to force or set as default all Waystones as Global. It's a small thing, but turning off the 'creative mode required to set waystones as global' gives my players control over which to set as global, and leaving that on means I have to run around and manually re-place all my player's waystones to set them as global - the former has caused problems, and the latter is workable but somewhat annoying.

Sharestones seem much better suited for your use case, Global Waystones were a workaround for Server Hubs and never meant to be player-controlled.

I see. Can you still use a Waystone to teleport to Sharestones? Or is the intended setup that you essentially have a single, global Waystone for people to teleport to, and then a Sharestone next to it for people to get access to the rest of the network?

Currently sharestones can only be teleported to from other sharestones. In a future update warp scrolls, warp stones and Waystones will also be able to teleport to Sharestones directly.
