In my 1st year Physics college course, Electric Field at a point is defined as $\vec E = \frac {\vec F}q $. However, during high school, it was defined as

An electric field is a region of space where a Coulomb force acts on a charged body placed in that region.

And Electric Field Intensity was defined as

Electric field intensity at a point in an electric field is the force per unit charge acting on a test charge at that point

The definition for electric field I am learning now seems to be what was previously defined as the electric field intensity.

My question is, what is the difference then between a field, and the intensity/strength of the field, and how can we define a field generally?

A electric field is a vector which can exert forces to electric charges. Electric field intensity is always defined over a surface and if you calculate the surface integral of the E field for some surface you will get the electric flux.
