I would accept 1.
I would prefer 2 without the initial "the".

Let's say each city has its own city-wide speed limit:
1. "The speed limit varies between cities."
2. "The speed limits vary between cities."
Definition 1 for "vary" of this dictionary which reads:
"to be different in different situations"
, which implies that a single characteristic, without it belonging to a specific thing, is being talked about, so sentence 1 should be the correct one.
But, definition 1a of the same dictionary reads:
"if two or more things vary, they are different from each other"
which implies that two or more characteristics, each belonging to a separate thing, are being talked about. So sentence 2 seems to be the correct one. What do native speakers think?

So, both versions are standard English?
Yes, I would accept either one.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
