At this point, any ringtone is considered cringy, at least by millennials. Every once in a while I'll hear one make a beep, and its owner exclaim "How dare you talk to me!" Hearing other people's phones is considered rude.

Phones should be set to vibrate. If it's on your person, or near to hand, that's all you need, and nobody else has to know.

Some people do need a sound -- perhaps things are urgent, or they leave their phone across the room. If so, you want a sound that's loud. It doesn't need to be fancy, but it does need to draw attention.
