I think currently it's either-or: Either you create account with email or with LNURL-Address, but you can't switch between those. 

Out of your list above I think I would do Breez. That's what I use for lnurl-auth and it works well. 

I signed up with email. So my concern is not recovery, but just a simple convenient cross-platform wallet that supports lnurl-auth that i can connect here.

Is there a plan to allow later connection to email (or some other form of recovery?)
