Godox have a pretty decent line of TTL flashes and TTL triggers for their entire flash line up. I personally own a Godox TT350S and I'm pretty happy about it for simple portrait and party photography. For studio photography I'd pick a trigger and dedicated studio flash (I tried to work with a second TT350S but it is not as convenient and powerful)
I'd advice you to research guide numbers to get an idea of how powerful you need your flash to be for your desired focal length.
