Speed Wallet. https://www.speed.app/

I make no claims other than I've used it a couple of times over the past week, it seemed fine. It's custodial. But maybe even better for a beginner would be using Wallet of Satoshi, with a vpn, as in an earlier comment.

I would not consider Phoenix beginner friendly, or very straightforward. Either that, or I'm a dummy. Receiving is a pain. Yes, I've looked at the FAQ and emailed support.

In terms of Alby - is that even possible, on a phone? Also last I heard, they had some new restrictions on some things (total amount you can store, number of transactions, etc).
