This is newbie talk, so don't kill me. I want to learn, but it seems so complicated.

I want to  - sell BTC for ETH, and then sell that ETH for more BTC than I started the trade with. Sounds like a simple way to start, yet I know it won't be.

My biggest concern is that there are so many exchanges. How the heck do I know which ones will pay me after I make an exchange? I know I have to check their reserve balance, but what else should I look for?

It all depends on what you mean by what you said "which ones will pay me after I make an exchange" but I personally select an exchange base on
1) Reputation
2) How fast is their withdrawal service and cost: You can not request a withdrawal on Binance and don't want to pay a huge transaction fee which is unfair.
3) Customer support.
4) Geographical area restriction.
