I always reccomend Blue wallet.

* self custodial

* on-chain

* lightning

* multi-sig

* watch only

* available for mobile and desktop

* good security (password, biometrics, plausible deniability)

* tor

* can connect to own nodes: Bitcoin, lightning and push notifications server

* etc.

Blue is easy to use and secure for beginners (everyone I reccomended it to, like it), but when theye get more advanced they can use more features.

The only flaw I find in it is quite long loading time.
