Special (small grain, high acutance or speed enhancing) developers are somewhat too uncontrollable for old film, the more so as the film may have aged to grow different properties across the roll's length.
HC-110 is generally considered the best off the shelf developer for severely expired film, being free from oddities, having very uniform development speed across film speeds and brands (so that guesses at the development time are easy) and already containing a anti-fogging additive. The other common recommendation is D-76/ID-11 with some added benzotriazole (Kodak anti-fogging #1).
For film exposed ages ago, two stage developers might be worth considering for their speed benefit, to regain the loss in latent image - but as they also tend to increase fogging, that is a last resort to recover near-dead film. When you expose old film now, you'd better decrease the speed you expose at, if a test proves the negatives to be too faint at nominal speed.
