I was going by the Wikipedia page that has a table from the FBI, but searching on the FBI website it has something even more specific on cities in FL:
https://ucr.fbi.gov/crime-in-the-u.s/2019/crime-in-the-u.s.-2019/topic-pages/tables/table-6
City of Jacksonville:
Population: 909,142 Murders:129 Rate: 14.2/100k
City of Miami:
Population: 480,505 Murders:43 Rate: 8.9/100k
City of Tampa:
Population: 400,501 Murders:31 Rate: 7.7/100k
City of Orlando:
Population: 292,120 Murders: 25 Rate: 8.6/100k
For some reason, NYC isn't on here. While still higher than NYC, these do vary from the Wikipedia site which may have gotten their data from another FBI source. Jacksonville/Orlando are higher while Miami/Tampa are lower than the Wikipedia source. My guess is that the Wikipedia source isn't solely based from 2019 FBI data, but used some sort of smoothing technique as when the totals are in the double digits murder rates can vary significantly year to year just based on a singular outlier event.
If looking at larger geographic areas, they have measurements of that as well for these FL cities. First, you have to define what is the geographic area. However, I thought you were mostly concerned about the city of NYC, because that's where the subway is. You can look at specific places in the NYC metro area and find high murder rates (like Newark) just as you can for almost all the major metro areas, but if you look at NYC collectively or the metro area collectively it's impossible to call it some sort of murderous cesspool compared to the rest of the country. Even with the recent uptick it's still a lot safer than it was back in say 1990.
