GrapheneOS for phone. Multiple user accounts to further isolate apps.
Pi-hole as a recursive dns server with dnssec also using unbound for DoT for home network and IoT devices.
AirVPN for my daily driver devices and windscribe for other devices that may need a vpn.
Proton for E2EE mail and storage. SimpleLogin for alias emails.
Try to use FOSS apps and block trackers where I can. Feeder (RSS), Squawker (Twitter frontend), and Eternity (Lemmy app) have replaced all the more popular social media apps.
Bitwarden for password manager.
For browsers I use Firefox with some settings tweaked or Mullvad (if I’m concerned about fingerprinting).
