Depends on where you have the trim set which is always a compromise. If the
trim is set so that there is no nose down trimming required after takeoff,
then it will take quite a bit of pull to get the aircraft to rotate and in
the initial climb. If the aircraft is trimmed so that only a moderate
amount of force is required to rotate then it will require pushing on the
yoke and retrimming after takeoff as the airplane accelerates.

The trim setting is correct for one speed and configuration (power and flap)
and since the airplane is accelerating, the trim is going to need to be
changed.

I've been leaving the trim neutral. Rotation is sluggish up to a
certain speed, then the plane pitches up rapidly if I try to rotate
beyond that speed. Thereafter, I must push on the stick to keep the
pitch angle within reason.

I take it that I should trim to hold the nose down a bit?

It just surprises me that the plane pitches up so quickly
(particularly the Baron 58). If I know it's going to do this, I can
adjust the stick as soon as the nose rises, but I was wondering if the
real aircraft would behave in the same way. I don't see small planes
taking off like that when I observe them from a distance.
