I think the value of standups depends a ton on the team's composition and maturity.

On a team with a lot of junior or low-performing devs who don't have the experience or the ability to keep themselves on track, or a team with a culture that discourages asking for help as needed, a daily standup can keep people from going down useless rabbit holes or unwittingly blocking one another or slacking off every day without anyone noticing.

On a team of mostly mid-level and senior devs who are experienced enough to work autonomously and who have a culture of communicating in real time as problems and updates come up, a daily standup is pure ceremony with no informational value. It breaks flow and reduces people's schedule flexibility for no benefit.

When I'm thinking about whether it makes sense to advocate for or against daily standups on a team, one angle I look at is aggregate time. On a team of, say, 6 people, a 15-minute daily standup eats 7.5 hours of engineering time a week just on the meetings themselves. The interruption and loss of focus is harder to quantify, but in some cases I don't even need to try to quantify it: when I ask myself, "Is the daily standup consistently saving us a full person-day of engineering time every week?" the answer is often such a clear "yes" or "no" that accounting for the cost of interruptions wouldn't change it.
