Welcome in advance to Boise. I just flew back from two weeks in Florida visiting our first grandchild so I know a little bit about where you are coming from and think you will truly enjoy your new chapter in life here in the Boise area. One thing you won't have to deal with here in Idaho are the toll roads. You will find a lot younger age demographic as well. On our first visit to Florida I had to ask my son what a Silver Alert was that I kept seeing on the highway reader boards (they are like an Amber alert for old people). You would find more cultural diversity in Orlando in a day than you could find in Idaho in a year; however for the most part, most people in Boise are very tolerant to others.
I have seen a quite a few job postings for various law enforcement positions here so hopefully it won't take long to find the right position for your husband. Here are a few links to consider:

There are also lots of other federal type positions that might be worth considering based here in Boise (one of the benefits of being the state capital).
They are building a few new hotels in the area so that should create people moving around creating new openings at existing locations too.
Hopefully you will have time to spend a day driving up to some of our local mountain communities, take some nature hikes, walk along the Boise River on the Greenbelt and try some of our local breweries, wineries or the new cider bar.
I would suggest scouting out the types of things you do for fun in Florida and see what we have here that is closest to it. Of course you won't find Disney, Sea World or Universal Studios here. Our closest theme parks are probably Silverwood in northern Idaho and in Salt Lake, Utah.
