In 2022, if the first date is going really, really, really, well and her face is voluntary inches from yours as you end the date and making focused eye contact with you, and you feel so compelled yourself - go for it (the kiss). That will set the tone or break it. It's a chemistry, timing, and balance thing. Most cases I think if you try to wait several weeks to have a bf/gf status discussion, you won't know where you stand chemistry wise. She might think you're not in to her. This is by no means the end all be all. Not every situation is the same. Call it conventional wisdom. But most importantly, be you. Follow your gut. Try to respond appropriately to the vibe she exudes.
