Career options

I’m a seventeen year old who has been completing work experience at various firms in finance/professional services and before I was quite keen on working in that industry due to the high pay and what I thought of as a fairly low demand career compared to other routes such as doctor etc.

But after completing work experience I’ve realised I absolutely hate the hustle culture in these companies where employees work past the 9-5 day. Is it unreasonable to expect an 8 hour job in these sectors as it was the norm at the companies I saw.

On that note, what career paths can guarantee a simple 9-5 with no work calls or commitments outside these hours?
