I could not find any reliable comparison table for max wind speed resistance. Can we compare them as numbers? It should not be so subjective.
Some websites even claim that architectural asphalt shingles can do 110mph while their great metal product goes as high as 120mph, which is ridiculous advertisement if they only offer 8% more wind resistance for 2x the price.
Which one can do 160mph?
I'm 7 miles inland from the beach in Florida.

Your best bet is to find a roof which satisfies Miami-Dade code - I believe it is the most stringent residential code regarding being better withstand high winds and hurricanes. IIRC it requires roofing wind load rated for 185-195 miles an hour wind
Have a good insurance too.
7 miles in-land in Florida doesn’t say much.
Is it Miami? Or Jax? Huge difference. If it is Jax - you could be overreacting…are you in high velocity zone?
Edit: check page 21 -60 of the link below: it is for roofing e-permit. You may glean some information - if you have a similar roof type. Pay attention to underlayment and nails types

There are some manufacturers mentioned.
I think the code was just updated last year - the e-permit - is from 2018?

Proper installation and inspection is the key.
