All your services should be using https. Vaultwarden in particular won’t even run without https unless you bypass a bunch of security measures.
This is how to setup local only and external https, I highly recommend this as a baseline setup for every homelab. It allows you to choose how much security you want on a per app basis and makes adding new apps trivially easy.
Why https if the traffic is already encrypted by the vpn?
Security in layers.
