As alredy mentioned, but also install wise , very easy compared to installing twrp and Micro-g etc. Also Installing GOS and sandboxed playstore in main profile, hand it to someone completely oblivious and they will have no problems using it as they would normally do on stock. Learning to use it in separate profiles is just a matter of getting used to it.
Graphene OS . Best you can get on Android.
I have runned all of them , graphene is is by far the easiest to get around for someone new
There is a reason there are tons of Debian distros. They all make a difference.
PeppermintOS everything you need and nothing you don’t. Debian based with extra on top. Runs on 2gb ram , fast. Click install and setup but all the terminal stuff you want.since everyone mentions mint , it was a while since I used it. Felt bloated , perhaps better now. I stil say peppermint even for someone coming directly from Windows
You can run any distro you like on it , but peppermint is is my favourite. Everything you need and nothing you don’t.
I’m no expert but webview is used anytime remote content is loaded I believe. Certainly you can open links in FF but webview is always there , and not so obvious things always load that way. Webview is baked inte the OS itself. No matter how much you degoogle. Bromite had another webview based on chrome but that’s all the alternative that exist as far as I know.
Chromium is still Foss. Google might have a stink and definitely tries to influence on the Foss part. But when it comes to vanadium I have no question about that everything is under a magnifying glass.
As I wrote elsewhere , all projects have their place and I do use FF, just not on android. I would be really happy if FF on mobile would be able to compete but I don’t see that happening until we have full Linux phones (that actually does everything android does)

Sandboxing is crap on Firefox (specially on android) . Google is really fucking good at security since they are well a huge multinational behemot. They know security. Security =/ privacy. When you are using android you are using Chrome webview no matter what browser you are using. So just piling on stuff instead of replacing things won’t be a good security practice.
Also the Google parts are optional , you don’t need Googles stuff to use chromium. Just like vanadium does.
If you are using Firefox on android you are using Firefox AND Chrome. Webview is chrome whatever browser you use. So using Firefox double the attack surface and weakens security since Firefox is not properly sandboxed.
Sure you could root and install microG , don’t see why but you can do it. GOS sanboxed playatore is a better option.
