What the normal people will use in the beginning is going to be non-custodial LN based solution like strike. Minimal fees, easy to use. If you get a bit more, move to custodial LN wallet/onchain transactions. More fees, more security and less trust. And once you have too much BTC start storing them in an offline cold storage.
If you aren’t holding the keys that control your funds the entire time, it’s a custodial service. If USD is involved in any form besides paper cash in your own hands, it’s a custodial service.
