No 1 source has complete official stats for all the ships,
and even the "official" sources have problems.
(Like the Akira-class carrier's bay doors being too small
to fit fighters thru them.)
A number of sites have SPECULATED stats for the ships.
Thus, for example, Danube-class runabouts either have
a top speed of Warp 4.7 or Warp 8.
(Warp 4.7 was stated on DS9-with a maximum theoretical
of Warp 5.0. Warp 8 was speculated based on the
performance of the things-like trips to Earth and back
from DS9.)
With that in mind, one site that may interest you is
