You pretty much got the foundational stuff plus a little more established. Aside from getting away from Apple, which you already mentioned, there’s not much more I can think of without going full tinfoil hat. The main thing, in my opinion, is just not being a wide open door and giving away your personal data freely. Sounds like you’re there, so long as you don’t have social media accounts.
More encryption is the only thing I would think worthy of mention since I don’t see that listed anywhere. Encrypted messengers, encrypted storage, encrypted emails.
