What part of Florida is closest to Texas?

Could you please clarify for me which area of Florida would be the most proximate to Texas? I'm curious to know which region of the Sunshine State borders closest to the Lone Star State, as I'm trying to plan a trip and want to ensure I'm navigating efficiently between the two. Is it the southern tip of Florida, perhaps NEAR Miami, or is it further north, closer to the Gulf Coast? I'd appreciate any insights you could provide to help me navigate this query.
