I use Home Assistant and Frigate for security cams. I have a rack mount server with Ubuntu that acts as a NAS with NFS for ipcam video and SFTP for SwiftBackup from my phone.

I don't host my own password manager but iirc you can self host Bitwarden (I use the hosted version). You can also setup Resilio or Syncthing to sync files from your phone like photos.

WireGuard with a domain that only has private ip addresses. Caddy to handle domain certs. I use a split tunnel so my phone is always connected to my local network at home. Everything is http even with private ip addresses

I use frigate and home assistant. I have unraid for storage. I use a small x86 box with openwrt for my router.

I use vault warden (open source version of Bitwarden) for passwords. It’s amazing. And you can use the native Bitwarden client
