I like Electrum, but I don't like opening my own channels. It has too many drawbacks. I now (only) have Phoenix Wallet left for LN: opening a channel is custodial, but after that it's non-custodial.
Never tried Phoenix Wallet, but according to the article I read Phoenix has an exchange feature that allows you to send money to regular Bitcoin wallets and wallets that can use Lightning.
Phoenix also has higher Lightning fees than similar wallets.
That's because Phoenix Wallet will ask for a lot of fees when it sees payments to regular Bitcoin Network addresses.
Have you not tried other LN Wallets such as Eclair Mobile with a development that is finalized Eclair is also built by the same developer as Phoenix which is the first Bitcoin Lightning Network Mobile Wallet launched on the market.
There are still several other wallets that are non-custodial such as Breez, ZAP etc.
