Any Dovo, Ralph Aust, TI, Böker, Revisor etc. will serve you well.
They can all be your go-to if you like them, I have a 6/8 round point Genco a plain Jane that is still one of my favorite blades.
I here people say entry level/beginners straight razor and there is really no such thing unless maybe it is one with a guard.
It is really about your preference in size, grind, and point.
I find my preference in grind and point floats around more than my preference in width.
Anything between 5/8 and 7/8 is what I personally like.
Pick one that appeals to you,
I know this is not much help but other than getting something of quality whether that be new or vintage it truly is about personal preference.

Pat
