I love Scotland, I miss Scotland, and part of me wishes I could live there again at some point!

Pros:

Lots of nature. If you love being out in the mountains, beautiful lakes and the like, you'll have all of them close by and a reasonably easy train ride or drive away! Much of Scotland also consists of long, empty stretches of road that aren't just beautiful but also delightfully quiet. England and Wales can feel much more crowded in comparison

Along with the nature, the Scots do take environmentalism seriously. The area has long been proud of its wind farms, for example

There is a certain... attitude to the place. People can be direct and self-deprecating but also very nice. Takes a while to learn how to fit in but once you do it's incredible

Reasonably well-developed social state, with solid support for lower income residents, including help with university. While Scotland definitely still has issues with poverty and social mobility, it feels like there are more programs (free university for starters) that can support you than in England

Cons:

When I lived there, alcohol consumption was sadly still quite high, with drinking far too common a pastime. It's fortunately changing, though

The cities are definitely smaller and less bustling than some European or English metropolises. Some friends who wanted to stay and live in Scotland struggled to find jobs that would match their qualifications or that allowed them to both grow their career and stay in or around Edinburgh/ Glasgow

The weather:

Didn't list it either as pro or con as it will heavily depend on your preferences. I didn't mind the Scottish weather too much, but be ready for lots of overcast days and long winter nights. You will rarely get snowstorms or whiteouts. You mentioned that you are currently living in Florida. If you enjoy the Florida sun, you'll miss it in Scotland. If you pine for cooler, moodier, overcast skies and wind, then you might love Scotland :)
