Granted, this space changes quickly; but, my current recommendation is minibits wallet for pure Cashu with nwc support.

Then, when ready to graduate larger amounts to something more secure, swap to liquid (and eventually to btc on-chain) via bull wallet. Liquid doesn't have the unilateral exit that a zeus embedded node has; but with Liquid's federated model, it seems pretty close - and I think the tradeoff of not having to manage node liquidity is worth it (unless you're really using lighting like all the time).

Also, bull wallet's Recoverbull encrypted seed vault is a pretty clever set of training wheels (though, I wouldn't recommend using it for cold storage amounts).
