Commuting distance recommendations

Hey everyone!

I've been loving my eBike for getting around, and it's really opened up my commuting options. I'm currently doing about 8 miles each way on my hardtail eMTB, which is mostly paved bike paths with a few gentle hills. I'm curious, what's everyone's "sweet spot" for eBike commuting distance? At what point do you feel like it's too far, or just right, considering factors like battery life, comfort, and time? Would love to hear your experiences!
