Food service downtown 53 ft trailer new driver

I don't have cdl yet, not permit either. I was planning to get the permit and then apply for Gordon, McLane etc. food service driver trainee program. I thought it's the fastest and cheapest way to get into trucking. But after reading a lot here on forum from experienced drivers(thank you by the way), I am little bit unsure to start with a food service company. My reasoning is this; Food service means that they send the driver downtown, back alley parking, narrow street driving and backing, constant traffic jams(I am at Dallas, Ft Worth area.) And I see that after reading here, even minor accidents would get me fired and make my life really hard to get hired again. So my question and concern is this; 53 or 40 ft trailer(really long trailers for narrow turn and streets) , all day downtown driving, rookie driver. Isn't this a recipe for disaster?
Or as a second option which I probably should do, go to a trucking school (find a financial aid first lol) then apply for tanker Hazmat companies, they have regional and or daily home positions. They really don't get into heavy traffic as much as food service guys.
Also, if there is anyone been to the food service trainee program, I would appreciate your comments too.

 

I know, right lol even after proper training, food service for a rookie driver 53 ft trailer in downtown Dallas looks really intimidating.

 

I really would love to start with tanker companies. That would be a little easier start for truck driving career compared to food service, I think.
By the way thank you for your comments in this forum, I have learned a lot from your knowledge even before getting the cdl.
