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?)

I'm new here, which lnurl-auth capable wallet should I link?

I recommend using Lightning login if you will be managing/backing up your own node key. If you lose your wallet, you won’t be able to login anymore.

All those wallets are fine but I’d pick the one you’re going to use the most.
