??? Set Points For Different Battery Types
I'm just learning, with a smidgen of comprehension thrown in, set points for charging batteries. Are the set points the same for ALL AGM batteries, for ALL FLOODED/WET batteries, for ALL GEL batter...

No that is not correct. A Lifeline jar would be compromised by treating it to the 13.6 volts from a PD converter, whereas a Full River would be happy. The Lifeline will eventually gas and it may vent. Once it has vented...well that lowers capacity.
Too low a voltage will quite happily sulfate an AGM, just as it will a flooded jar. Then you get into the tricky area of doing a "conditioning charge", which is AGM "speak" for desulfating.
If you want to have long life (and I need long life due to a beer budget), then one "dances on the needles" to the best of your knowledge and the limitations of the equipment.
The best I can do includes temperature compensation for two of four methods available to me for recharging. One method is rarely used (my old trusty PD 40 amp converter with wizard). The other non temperature compensated charging path is the alternator.

First, unless you do something REALLY stupid, you can not "dry out" an AGM battery. The water that electrolyzes re-combines back into water.
Second, having the charging voltage a couple of tenths lower than optimal will NOT cause any damage to an AGM battery; nada, none.
