Yep, I would also use high rail design for this kind of work. There was a dilemma for me as well, when I was trying to make such tool, a I was trying to make it look like Bosch PR20EV Colt ( from here: https://www.woodroutersreviews.com/ ), because it very reliable and has design. which anyone can use with ease. It can work in any condition, no matter what kind of wood processing work you would do.
