> 1. Free ... 4. Takes care of most important backend stuff (forms and webhooks)
From my reading of https://www.netlify.com/pricing/#forms you will need to pay $19/month/site (!) just to collect the data from 1000 form submissions. By the time you have a couple of sites like this the price is already way too much for me and anyone else with basic backend knowledge. I hope I've misunderstood.
