Solder clevises at the servo end, threaded clevises or ball links at the control surface end, except quick connectors at the business end of the throttle.

In tight quarters, such as a nose wheel control buried inside a cowling with a horn that ends up very close to a fire wall, I have tapped a quick connector to accept a threaded rod. Allows you to adjust the length of the control rod from the servo end and eliminate a conflict between a clevis and the firewall.
