The most common waypoint label is, unsurprisingly, +X01, with 8771 occurrences.
In 11th place, with 1827 occurrences, is the most common visible point label, End.
Our next visible labels are exits 1 thru 5, at 22nd thru 26th place, with 1004-1141 occurrences.
Three more shaping point labels, and then there are 960 MainSts, landing it 30th place.
The next visible one that's not an exit number is A1, numbering 721.
From there, it's a mix of shaping points & exit numbers along with A2, A4, A6 & A3, until US1 in 81st place with 378 cases.
Arguably the first not-completely-obvious one: there are 344 StaRds, landing it 87th place.
