For pure casters (CNJ, THM, and presumably ACN, as well as their jobs), sink all of your points into your "efficacy" stat, since you'll only rarely be low on MP and the effects of an increase in your MP stat are relatively small. So, that's MND for healers and INT for DD.
For melee DD, every point should go into your "efficacy" stat (STR for LNC and PUG, DEX for ARC) because that's your only job. In solo play, you'll get more mileage out of maximizing damage due to your weak defenses.
For tanks, it's not quite as clear-cut right now. VIT would seem a good choice so you can soak up more damage, but unless you get an effect that gives you a percentage increase to HP, the effects of added VIT seem relatively useless versus the effects of a competent healer. Block rate (DEX) is an interesting question, and I'm not sure all the math is in on it yet; because XIV doesn't seem to use a "hit table" system like WoW, block rate doesn't have any special unexpected effects. In general, I tend to prefer block rate over block strength (consistent mitigation is easier to deal with than spiky but large mitigation, IMO), but it also seems like added DEX doesn't increase your block rate that much.
So, that leaves STR. For an MRD, a lot of your threat is based on your damage output, so there's a strong argument for maximizing STR for them. For GLA, I personally think block rate is too hard to raise via DEX to outweigh the multiple benefits of STR (block strength and damage, which includes threat on attacks or combos with "additional enmity" as an effect).
So, in short, it looks like you should always put your points in your "efficacy" stat, which is MND for CNJ; INT for THM; DEX for ARC; and STR for LNC, PUG, MRD, and GLA.
