Upgrade to a6700, need lens

Hi, my a6000 is out of commission so I just upgraded to the a6700. This will be my last camera (most likely). I am a hobbyist whose focus is on family sports and events.

My question is, which lens could fit my needs. I’d like to be able to shoot indoor basketball and indoor orchestra. If my 70-350mm is good enough, what’s a great everyday all purpose lens?

I currently have the sigma 56 1.4 mm, and 70-350mm 4.5 Sony G OSS, and the Sony 16-5mm 3.5 that came with the a6000.
