DS224+ will likely give you really good performance based on what you mentioned. Although the max RAM (6GB) could potentially be a concern if you run too many containers

“Known to collect” is going to be vastly different from what’s actually being collected. It’s more realistically just serving ads, getting some crash/error reporting. But because it’s all under Google, it’s going to show up as Google. DDG/other blockers won’t know the difference.
