You can also look at flights to FCO and take the train to Florence. Under current schedules (they aren't posted yet for June), there's a direct train from the FCO airport station leaving at 13.53, taking 2 hrs. 18, and frequent connections in Rome taking just a few minutes more. It may be easier than connecting in a third country to FLR, often with a tight time to have Schengen passport controls, and the connecting country possibly having extra COVID rules.
