New to eBikes - where to start?

Hey everyone!

I'm completely new to the eBike world and feeling a bit overwhelmed by all the options out there. I'm looking to buy my first eBike soon, mostly for commuting about 10 miles round trip on paved roads, maybe some light gravel paths on weekends. What are the absolute must-knows for a beginner looking to make a smart purchase? Any specific types or features I should prioritize, or pitfalls to avoid?
