I don't think it's possible to give recommendations because we don't know yet how exactly the release version of the game will be.
Even those of us who have played that kind of games for a while, have followed BG3 and watched videos or played the Early Access will most likely spend days on character creation.
Usually the best approach is to read enough information during character creation, pick something you personally gravitate towards and not something that will have the most powerful build.
You'll play with a party of 4, so skills will complement each other, and it's not an MMO where you play against other people, so optimized builds aren't the main thing. It's a long game, full of choices, so the most important decision is "what kind of character do I want to play".
The emotional, conflicted half-orc who wants to be a paladin? The sneaky little halfling who steals everything that isn't nailed down but has a heart for people? The flashy bard who gets through tough spots with charisma and persuasion?
The fierce big strong fighter?
Those are few examples and maybe tropes I could just come up with, but maybe you get the idea:
Going through the character creation with the sense of "Who is this person I am steering through the game?" matters more to enjoy a good RPG than perfect builds. There will be respec options later to correct mistakes in leveling, the difficulty can be adjusted on the fly, and with a balanced party there are always multiple ways to solve even difficult fights, especially in turn-based combat where you have time to think and decide, compared to action games for example.
I still haven't decided myself which race and class to settle on. Bard of Swords, Arcane Trickster, other rogue, they're still on the list, and probably some half-elf, but I still haven't outruled tiefling either.
If decisions about character type are difficult but someone is not the type who prefers a custom character, in Divinity: Original Sin 2 (Larian's last game) the origin characters were great, because they made you experience the story through their eyes, tied more deeply to it through their unique perspective.
The problem I have with this approach in BG3 is that I don't feel that kind of connection to most of those origin characters (yet, maybe), and if I pick, for example, the only one I like enough, it means I can't pick that person as companion or even potential romance option anymore.
As for actual builds... we will certainly discuss them starting from August 3. At this point, we have no idea how it's going to work. And that's exciting!
