To be fair, it's very hard to make a (single-classed) bad character in 5e. Pretty much the only two places where you can go wrong are:
- Choosing poor stats. BG3 should indicate what your important stats are though, and when in doubt boost your main score to 16, and Dex and Con to 14 or maybe 12.
- Choosing poor spells. Luckily, every level up you can choose new spells. Additionally, there are plenty of scrolls to use throughout the game.

One feature of 5e is that you don't make that many choices when leveling up. You essentially only choose your spells, your subclass at level 3, and your ASI/feats at levels 4, 8, and 12. D&D 5e doesn't really have the whole "there are so many options, but many of them are trap options resulting in your building an ineffective character" that earlier editions/pathfinder had.
