Many people manage to mountain bike with clipless pedals where emergency exits are a regular occurrence. Though mtb pedals are generally bit easier to get in and out of than rod pedals. I know a lot of people who road bike with mtb clipless systems.
OTOH, I do think the benefits are a bit overstated. They make a real difference during high intensity bursts (so they are a no-brainer in competitive situations) which is really the only time most people are actually pulling up on the pedals, but outside of that, not so much outside of simply what feels more comfortable.
I will also say that if you haven’t tried modern, good flat pedals and shoes, you really don’t know what flats can deliver. Any time I hear someone talking about slipping off flat pedals on the road, I know they have not tried modern offerings.
Just use what you are comfortable with… and then be a d!(k about it.
