Here’s mine, complete with FPV. Reasons for servos near the tail: Easy access for adjustment, shorter control linkages, better for CG.
I do not like long linkages, and guide tubes as they cause binding, and should the guide tubes break free, you no longer have that flight control. Why bury the servo deep inside? For looks? I’m all about practicality. I can understand as being a newbie, not wanting to stray from the plans. As your experience grows, you will develop your own methods and methodology. This hobby is all about experimenting and having fun
