To try to get a clue as to the asymptotic behavior of all these binary-algebra counts, I decided to compare them to the asymptotic behavior of the general number of groupoids. I looked for something with form
n^(c*n^2) / n!
where I tried to find c.
For quasigroups and loops, it is roughly 1/2.
For semigroups, it is roughly 1/4.
For commutative semigroups, it it roughly 3/16.
For monoids, both in general and commutative, it is roughly 1/8.

For groups, however, c tends to 0, and their rate of increase is much less. The counts of them jump around quite a lot, and those counts are very sensitive to the exponents of the order's prime factors. So it's hard to make a simple statement.
