Victoria Rules
I force some classes (e.g. Paladins, Cavaliers, Monks, Assassins, Necromancers) to be particular alignments or alignment ranges, but in my games any PC alignment is allowed.
I won't allow some particular race-class combinations, partly for setting reasons, partly personal preference, and partly because I've learned that when certain races can be certain classes balance kinda goes out the window.
Were I to DM different editions of D&D there's some classes I'd flat-out never allow: Gunslinger (hard to be one without gunpowder, which don't exist 'round here); Warlord (at least as written, as I don't like martial healing); and a bunch of prestige classes that just seem a bit OTT. I'd also look at combining some classes e.g. Sorcerer and Warlock into just one, and try to cut down overall the number of caster classes while maybe adding a few non-casters.
All that said, the classes that are allowed or not allowed do help inform various elements of the setting, and vice-versa e.g. the Gunslinger example above.
