I doubt any force field will give you any meaningful differences at such
a small temperature interval.

There's no real way to know. Different force fields do well at different
things. Simulating "a protein" can mean a lot of different things. Are
you simulating a well-folded protein with a stable tertiary structure?
If so, just about any modern force field will perform equivalently. Are
you trying to fold a protein or simulate something intrinsically
disordered? Then there are force fields that do better than others, but
the choice must be yours based on a thorough review of available
literature; it's not something that strangers on an Internet forum can
conclude for you :)
