2 players 1 game field in shooter/card game

We are developing a game for Unity, space shooter/tactics with cards and abilities. There is always 1 vs 1 match, like in regular card game (Hearthstone etc.), but game field is more like RTS. This field contains active objects, player's ships and projectiles. Need to set camera for each players with their own UI interface.

What's the best way to implement such a thing? Two canvases with UI for each player or what? Need your advice...

Any help and answers would be appreciated.
