Thanks for all the info! I ended up changing both (servers and registration) over to Cloudflare. It was annoying that proxies were on by default and I had to turn them off manually, and the website is kind of fiddly to be honest (I had to input my payment info three times), but overall I trust them to have good security practices, and they have a reasonable-enough track record when it comes to disputes and business dealings. I feel like I know what I'm getting, and all I really want is for my personal site and email to do what I need and not get compromised.
