What's the use case?

Are you asking about wallet for accepting bitcoin / point-of-sale, or for payments.   And if for payments, are you wanting on-off payments (manual) or batch / automated payments? 

Are you asking about self-custody options, or custodial services?

Are you wanting multisig?

Is there customer accounts involved (e.g., needing trust account(s))?
