Answer 1

There are 5 standard languages in IEC 61131-3 and the Ladder Diagram language is the most popular in general but the most appropriate language seems to depend more on context.

If you're starting some new PLC code at a company, let 2 things determine the language you use.
1. The kind of PLC task you're working on. Generally pick the simplest language for the task.
2. The language(s) used by the company on past PLC programming tasks. Try to be consistent. Try to make your language and the code you create easier to understand by making it more familiar.

If you're planning to study one before applying for PLC programming jobs, check some local job postings or network with other PLC programmers in your area to see what is most popular there. I would study all 5 to get at least the basics and enough knowledge to quickly get productive with each.
