>>21406016 (OP)For Chocolate Chip, I've literally baked dozens of different internet batches against each other over the years (Serious Eats, Cooks Illustrated, Bon Appรฉtit, Sally's Baking Addiction, etc) and this was the best I've yet found among the bunch:

1/2 cup granulated sugar
2 tsp vanilla extract

1/2 tsp fresh lemon juice

Updated and simplifies the dough with straight AP flour instead of taking a page from Jacques "Mr. Chocolate" Torres cookbook by employing a mix of Cake & Bread flours to dial in the exact protein/gluten amount for the perfect yielding bite and chew. I personally divide the recommended chocolate chip amount in 50/50 semisweet & bittersweet chips.
I have yet to experiment with a recipes that incorporates toffee bits into the dough which supposedly boosts the caramelized sweetness:

And going to the extreme degree, Sugarologie has a promising recipe also on my TO-DO list that incorporates Dulce de Leche into the butter browning step to give the caramelized outside flavor of a well-bronzed cookie into the entire thing at any level of baked softness:
