Please do not use any Chromium forks if you care about privacy and an open web. Cromite uses the Chromium engine, which is by Google.
“But Chromium is open source, so that means good, no?”: Not always. Developing a browser is very hard and requires a lot of time and resources. Therefore, even when you can fork Chromium in theory, maintaining this separate fork becomes incredibly difficult. Google of course does not allow any privacy centric code to be pushed to the Chromium codebase. It in fact, does the opposite. Look at the ManifestV3 drama for instance. The solution to all of this is using Firefox mobile or forks of it.
What security considerations are you mentioning? The only slight drawbacks that I see in the listed source are privacy ones. Those too can be mitigated by extensions. In my experience, Fdroid Fennec has been very stable and decently fast.
