I always onboard with breez and, kill me, Coinbase wallet (not the exchange). Because they're easy for noobs. Both are non-custodial. While I do have them write their 12-24 words down so they understand the concept those wallets don't necessarily require that.  I know it's bad letting them rely on a Google drive backup but I do warn them. That's all I can do.  

Only issue I have with breez, and I suspect Zeus will suffer this, is a clear guide for noobs on what to do when their channel to the lsp is closed. Breez mentions the app will guide folk on how to claim their coin but I've seen folk delete the app thinking a reinstall would fix it which only makes things worse. Other than that I think the lsp route is the way to go for noobs and self custody. It's progressed far enough that I can't see why people still use custodial solutions. LN Addresses were the only missing piece and you have that covered now.
