Solenoids

ebay. Typically between 10 to 20mm stroke.

Can you adjust a solenoid or is it purely an on/off deal?

Basically, can you use it as a light linear actuator...

Lol no

For small service most people use relays or mosfets

You can adjust the force by varying the current passing through it, but you can't fundamentally finitely control position. I suppose its possible to add a feedback circuit to turn it into a simple linear servo, but AFAIK there's nothing like that commercially available.
