Every F1 team has hundreds of engineers that works on specific part, but does one person in the end decide which part will be produced and installed on the car?
Are technical decisions in F1 teams "authoritarian" or "democratic"?
No different than any other company and largely depends on the leader.
Usually good practices would prescribe that unless you do the work, you should refrain from “adding too much value” as various leadership books recommend. Generally the CTO wants to optimize for the team working their best and they do when they work on their ideas.
It is a fine line for the CTO to perform an inception of his/her ideas into their team and then allow the team to execute based on high level measurable and specific goals.
Alternatives are usually micromanagement and being authoritarian only really works if the CTO knows everything already and wants to move very fast, but usually it’s still not that easy anyway and they may lose the team on the way to implement, which could end anyway in a poor result.
None of this is easy to do and it’s very intentional from the leader, it’s extremely easy to become “stubborn” and “force” the team to do what you want, which you really shouldn’t.
As far as decisions go, there is usually never decision by committee in good teams, data decides, and delegation is the best approach.
