One of the only big downsides I've noticed with GrapheneOS is that several banking apps don't work with it at all thanks to being tied to Google's verification ecosystem. Luckily I have hardware 2FA keys from my bank so I can authenticate using that. It also slightly decreases the suck-factor from whenever the phone decides to fly off down a drain. This may not be the case for you, so do your research on what you nee…
Author is installing Google Play Services it seems, wouldn't that work around this? In any case, for me this also sort of defeats the purpose: I'd rather break free from Google and Apple, not just (stock) Android and iOS.
Not really. On GrapheneOS, the Play Services/Play Store run as sandboxed apps, i.e. they are not system apps like on Android. They just run like a normal, unprivileged app. That's a lot better than on Android.

If you want to break free, you don't have to install the Play Services / Play Store on GrapheneOS, just like you don't have to install microG on LineageOS. There is a misconception that microG is better than sandboxed Play, but I disagree. With microG, your apps still connect to the Google servers, so you're not "breaking free".
