Indeed we don't ID here, but generally speaking it's worth realizing that the far majority of shrooms are Cubensis (and apart from possible exceptions like PE, the strain should not really matter), which are pretty 'stocky' and wrinkled bronze-golden caps. Other usual suspects like Pan Cyan look like pieces of dark straw by comparison, so thin and tiny.
So usually when talking dosage, we assume Cubensis. If you have something else, find out what it is and use the Shroomery dosage calculator to help you further.
In my experience you can hardly get a trip without the communication weirdness so you would kinda have to choose and accept that there is a downside. I think until about 2 grams it can feel more stoney (already some slight weirdness though) and kinda trippy, while 3 is more likely to become a fuller trip. They are natural products so there is an uncertain factor with the potency.
Acid is quite different in my opinion, it is easier IMO to find a dose to trip on that and stay functional and communicative.
Considering the social setting, aim low. Reserve the real trippiness for some other time.
