Barbarians get an initiative bonus, and theres a feat that gives +5 and surprise immunity.
Initiative itself is based off dex, so you could also have 16 dex on the barb, or use the 18 dex gauntlets.
If you really need speech skills on top as well you could dump dex, use the gloves, and go 20 str, 16 con, 16 cha?
For me Astarion with 20 dex always goes first even in act 3 encounters even without any investment in initiative, I think some of his gear also has +1 initiative too, so if speech stuff isn't necessary, go in for a sneak hit first with him then bring in the others. This can work even better if you make him an assassin, and is pretty much what that subclass is designed to do, one sneak hit first and you get another bonus action right after for a second attack.
