How much insurance coverage is needed in Florida?

[Chad Hack]

We have purchased a detached condo in Florida. It is covered by an HOA and then we get the "walls-in" policy. For the contents coverage, is there a rule of thumb for how much coverage we should have for a 3 bedroom/2 bathroom 1600 sqft detached condo? It's a $500k condo so replacement costs would be for higher-end furnishings. Is there a good rule of thumb that anyone uses for determining insurance coverages? Thank you as always.
