Hi there!
Unfortunately there's no definitive answer to this question. Choosing a keyword that should be "easy" to rank for doesn't always mean that you will rank for it. There are a few problem with that thought process. 1) There are probably other people doing the same research trying to rank for the same "easy" keyword as you. While that is still a less competitive term, you are still competing with the other websites that are optimized for this keyword. 2) You can't just add a keyword to a website and expect to rank for it.
Are you trying to rank your homepage? Or a new blog/article? It would likely be easier to get a homepage to rank for an "easy" keyword than a new blog post because your homepage is likely to have a higher page authority. What is your website's domain authority? Is it comparable to the other websites that are already ranking for this term?
There are a variety of factors that go into rankings, and even if you are focusing on one specific term, you should also spend time improving the rest of your website as well to ensure you have the best possible chance of ranking in the SERPs.
Hope this helps!
