All of your inputs/thoughts helped me to find real experts out there. Their name is The Things Network. For example and as brought up from @bwildenhain here is their link to duty-cycle. There is Forum as well, etc.
Not Suitable for LoRaWAN:
Realtime data - you can only send small packets every couple of minutes
Phone calls - you can do that with GPRS/3G/LTE
Controlling lights in your house - check out ZigBee or BlueTooth
Sending photos, watching Netflix - check out WiFi
Another one that I found out (having some time this evening) is pretty much official thing, REC 70-03 (the best info, IMHO) on what is going on within EU. @StevenR please take a look at ANNEX 1 link there. Another relevant EU regulations are ETSI EN 300 220-1 V3.1.1 (2017-02) and ETSI EN 300 220-2 V3.2.1 (2018-06). My comments mostly cover ITU Region 1. Useful ITU RADIO Regulations presentation from 2018 is here.
