Society has made many of what were originally the most common places to meet your future spouse now taboo to ask someone out. For example, before dating apps, something like 30-40% of relationships leading to marriage started in the workplace.
My personal experience, the boring sexual harassment training, and talking to the AI, suggests that asking out a coworker at the same level of the org chart with whom you don't closely work is not considered really problematic, especially among young people.
You can't ask out someone you supervise and its considered a little socially risky to get involved with someone who you work with really closely, but nothing seems to prevent coworkers from asking each-other out, as far as I can tell.
