An aside, but I found FreeCAD to be a real pain. The dependency tracking across sketches is really quite horrid. If I have sketch2 linked to sketch1, and I delete a line in sketch1, it will arbitrarily reassign all the sketch2->sketch1 dependencies. Maybe they fixed that since I've used it, but I've transferred over to Onshape for all my hobby stuff...

EDIT: looks like they finally addressed the topological naming problem, I guess I better give it a second chance!

Solvespace handles topological naming almost flawlessly. Even in a repeat group, the first and last copies of a sketch are "named" first and last rather than given a number. This is because constraints are often applied to those copies. This way they won't break if you go back and change the number of copies.
