Also looking at weather effects, it seems Nov 7 1861 in Belmont was a totally clear day, yet the weather versions indicate some probability of snow. Wheeling out ChatGPT to check weather reports indicated no snow on the day, it even checked Grant's and McClernand's journals to confirm.
I will not comment on the value of individual scenarios but the variety is there to give people choices. If a scenario has 'hist' or 'historical' in its title then this is usually the scenario that the designer thinks best replicates the historical situation. To see the differences between them there is often an indication in the Description for each scenario. Your example is a little unusual as there are two 'historical' scenarios (plus their weather variants). However, if you look at the Description you will see that 2a says:
'Some Abatis has been removed and breastworks added.'
Perhaps there is some uncertainty over what defences were historically present. Or perhaps it is simply to give the players a choice [I'd imagine it would be a little easier for the attacker if the abatis are removed.]
The same for 'Alter OB' and 'Graphics'; they are simply there to give players some choices about how they view/play the battle.
"Also looking at weather effects, it seems Nov 7 1861 in Belmont was a totally clear day, yet the weather versions indicate some probability of snow ..."Again, it's about choice. Perhaps there was a chance of snow and other things so they have been allowed for to enable someone to test such 'what ifs'.

Sometimes the Campaign Notes for different titles can also provide insight into why some choices were made.
Finally, you may also come across some odd titles that include terms like c1u1, c1u3 or c3u1. I only found out last year what those terms mean. They are scenarios from the campaign games in the titles. For example, c3u1 for a specific battle refers to the Confederate third choice (c3) and the Union first choice (u1). Thus, many battles (from the campaign game) will have different variants and, yes, there are usually [I hate to say always] weather variants of each of them.
