Unfortunately, a lot of official writing tends to describe these things very generally. Not to mention, the descriptions of the use and functions of specific technologies are very inconsistent throughout the Star Wars universe. The first thing I would do is get really familiar with some terminology to describe the systems of a starfighter. Once you understand what each part does, it’s much easier to describe what a pilot is doing accurately (and a lot of this stuff is not specific to any one starfighter, and will work with the Resistance T-70 X-wings even though they don’t have a lot of known specifications). The best way to get a feel for it is to just read some of the books (the X-Wing series is particularly good for this), but obviously no one wants to read a dozen books to write a scene or two, so I would recommend taking a look at the “starships” section of the Vocab List (which I’ve just updated) for some of the terminology. It is by no means a complete list, so if you have the time you could also look through the Wookieepedia categories for starship components (which includes stuff like engines and weapons, which is still a useful thing to know how to describe) and starship computer systems.

More practically, this is a photo of a T-70 X-wing’s cockpit. I find it nice to have an idea of where things are located, even if you can only pick out a couple components. I have not been able to find a labelled diagram of a cockpit, but I will post if I find one.
At the end of the day, I’m a strong advocate for picking out whatever canon you want and tossing what you don’t, so I wouldn’t worry too much about whether you can describe the exact mechanisms of using a starfighter’s console. It can be nice to have a very general explanation of what’s going on, because too many technical terms that the reader may or may not know can really mess with the flow of a story.
Hope that helps a bit!
