Everyone has already given you a different opinion, yet you want more of them? ;) Ok. My yard is small in size, so I would pick four dwarf ones for that reason. With a lot of land, I would go for the larger.

Citrus Orange 'Washington Navel' Dwarf
Citrus Orange 'Valencia' Dwarf
Citrus Lemon 'Eureka' Dwarf
Citrus Mandarin 'Satsuma' Dwarf ('Owari')

I love the tart of real lemons, so would choose the Eureka over the watered-down Meyer. You should choose what your taste buds like.

And I would love to have a producing key lime. But, I tried it and every season it would dump all of the fruit when they were a little under-sized and under ripe. I finally yanked the plant and purchase my limes from the same markets I had to use when I had a lime planted. A compact arbutus now lives on the former lime's real estate.

I used to have a Eureka lemon up till about 6 months ago.. But I grew tired of battling the leaf miner and now just purchase large bags of lemons at Costco. I take the zest, juice them, and store everything in the freezer for use as needed.

Choisya shrubs were planted to keep the giant swallowtail butterflies happy.

So that is my what-n-whys. Since you asked. :) Good luck with your trees! It is wonderful to be able to go out back and pick fresh fruit.

I have a very similar selection to yours. The Valencia was here when I bought the house over 25 years ago, and it it quite large. I love orange juice, so I'm happy with a large tree, and it provides shade in the afternoon.
The navel didn't produce well and I removed it. The Myer lemon is great. You can get a lot of lemons almost year round from a fairly small tree. Mine isn't even up to my waist yet and produces lots of lemons. I chose this variety because it is called for in many recipes I like.
I also have a dwarf Rio Red grapefruit and a dward Kishu mandarin, which is similar to the Satsuma. They all do well in Santa Ana. Another variety of grapefruit might do better than the Rio Red, but I am getting fruit. The Kishu mandarin is new, so I'll have to wait to see how it works out.
If you like limes, Bearss limes grow better in Southern California.
