My understanding is that the terms "indica" and "sativa" have sort of lost their meaning a little bit. I believe those terms technically refer to the height of the stem, and that it doesn't necessarily translate to the effects of the high the way we once thought it did.
For example, I always had the same understanding of indica as you described, and I would solely buy indica gummies. They would give me a pretty "heavy" high, full body but mostly in my head, and I would wake up lethargic and often with a headache. I switched to a "sativa" of the same brand, and got a very nice full body high, but much lighter, very relaxing, and would sleep very well and wake up feeling refreshed.
Anyway, all that to say, different strains have different effects, and often the description from the dispensary can give you a good idea of the effects they are intended to have.
