It may have been a little too cool for your tomato seedlings to take off rapidly. They should do better when the nights are consistently above 50°. If not it could be a fertility or other issue with the potting mix.
The container you want to grow them in is the large square one, correct? It currently has a clump of basil and a couple young clumps of cilantro?
The reason I suggested the Sakura was because it said it grows in a tight space. If you want to have room to grow other plants with the tomato it needs to be compact. There are other choices though.
There are catalogs which sell 100's of tomato varieties and they make every one sound irresistible! So I can easily imagine being tempted by Matt's Wild Cherry.
I'm actually not the best person to advise you on tomato variety choices for your climate. I found a link for tomato growing in Florida that might be more helpful.

They briefly mention indeterminate vs determinate. The indeterminate ones continue growing at the tips of the shoots, producing leaves and additional flower/fruit clusters until something stops them. Here, it's usually frosts. There, it might be heat. Even if the plant continues to grow and produce flowers, they may not set fruit when the temperatures are high (over about 85°). The vines are potentially perennial.
Determinate ones grow for a limited time (often into a bushy shape rather than a vine) then set fruit all at once and are finished. These are true annuals. They're usually grown for harvesting a large number at once, such as for canning.
The article mentions Sun Gold (cherry), Black Cherry, and Juliet (red, a little larger, salad sized). I have grown each of these in containers similar in size to yours and obtained reasonable production. The plants won't grow as large or produce as much as in larger containers, but enough if you only need a few for fresh use every day or so.
Seeds for those are readily available in most seed catalogs and aren't expensive.
The Everglades tomato mentioned in the article sounds like it is similar to Matt's Wild Cherry. I'm not familiar with it.
