Sample rate

Hello. I have a little question here.

Say I want to use NI Session strings in my project, which are sampled at 44.1 kHz as the specification says. But all the other instruments I’m gonna use are synthesizers and my overall project sample rate is set to 48 kHz. So, will there be any case of resampling? Should I set my overall project sample rate at 44.1 kHz too in this case? Same question goes for the bit-depth. Shouldn’t all these parameters of samplers/project settings/audio intrface coincide? Otherwise I feel like making a flac file out of mp3, which doesn’t make sense at all.

As my nickname says i’m quite a newcomer into all this music-making, therefore sorry if I posted a stupid question and in the wrong thread.
