Hey, welcome and have fun.
You can play anything you want. What did you like in the old BG games - which class or race? Maybe try that for first playthrough.
I would also recommend to not rush things or get yourself spoiled. No matter what you do, you can always end the game, so don't be worried to get stuck.
My personal race/class combo is halfling bard, but really everything is a good choice, just make sure, you have fun.
And I would recommend to play without mods for your first playthrough. ANd maybe start with a custom character and not an origin, especially not Dark Urge on first playthrough.
