I actually don't have a lot of worker placements either, but the one I do have, I really enjoy and recommend: Yokohama.

I don't have a lot of basis for comparison, but I think it's interesting that the workers also act as the paths that your president can move through to activate a space, so you have to balance placing your workers in places you want to eventually produce while also placing them in tiles that will let you travel to your target space.
Simultaneously, having more workers on a space when it is activated gives higher return, so there are interesting decisions regarding waiting to activate a space when you have more workers on it or activating it early to get the resource you need.
There are quite a few more smaller mechanics that are nice additions. For example, there are also some race mechanics that give you a small incentive to be the first to activate a space, research technologies to make production more efficient, and building mechanics. All work together to make a great experience.
