Ask if the dwarf trees are on Flying Dragon rootstock. If so that would be my choice for most of the varieties. The Key lime and the Variegated Pink Eureka I believe would make the best ornamental trees. The Gold nugget produces a great piece of fruit that ripens in a different month than most of the other varieties. The Midnight is a seedless valencia that matures during the summer. The satsuma makes a small tree and is slow growing so a dwarf one may take forever to make a decent tree. The pummelo will be very large fruits that are pretty dry on the inside(not for everyone, tho I like them). The Palestine Sweet lime are usually very thorny and the fruit is acidless so for most it doesn't have much flavor. Cara Cara navel is very similar to a Washingtonal navel but with the extra benefit of having pigmented flesh. Minneola's have a pretty strong and tart flavor, again not to everyone's liking. Then the Moro Blood Orange if grown in a fairly hot climate can produce some dramatically dark red fleshed fruits.

Some of it says Flying Dragon others say Trifoliate. Most of the large sizes I want say Trifoliate. Is that good or bad?

You shouldn't have to prune any of the citrus trees, but if you get a large tree such as a grapefruit or pummelo, then it might be difficult to get the fruit off the top of the tree. I personally would choose dwarf varieties for your situation.

Here are the 5 I would choose, trying to keep a variety of both taste and harvest time:
1.) The Fruit Salad tree, just because you said it's one you definitely want...this one may need pruning to keep the tree growing evenly from the different grafts
2.) Moro Blood Orange - my favorite tasting orange, plus interesting fruit color. I ate mine on Christmas in Texas
3.) Mexican Lime - small size, blooms and fruit year-round
4.) Golden Nugget Mandarin - seedless and very late to ripen (like March), so that complements the Honey Mandarin on the salad tree.
5.) Minneola Tangelo - unique flavor to everything else planted

I would also strongly recommend tasting these fruits before putting in a tree. Have you tried a Tangelo, and do you like them? Do you use a lot of lemons/limes in cooking and seasoning? Etc. Obviously, don't plant a tree if you don't particularly like the fruit!

OK based on all your comments, here is my final list of citrus:

Salad Citrus standard
Owari Satsuma standard
Calamondin standard
Pink Lemonade  dwarf
Mexican Key Lime Dwarf
Melwa Kumquat dwarf
Moro Blood dwarf
Meyer Lemon dwarf
Calamondin

In addition I am getting:
4 in one Peach
4 in one Peach/Plum/Apricot
Fig Flanders
Mango Mallika
Mango Alphonso

I am still in two minds about getting a Reed Avocado. Let's see if there will be enough space. Will post pics when they are all planted. Wish me luck!
