Muun is one of the most friendly, privacy enhanced option since they do some receiver stealth via fake pubkey/channel rotation - out of all the ones I’ve researched so far.

For custodial non kyc, you’ve got a few like the telegram lightning bot, BlueWallet, and wallet of Satoshi.

Liquid is not going to help you if you’re supposed to be accepting bitcoin / lightning, but honestly at this point the law seems very unenforced to the point where people can do whatever they want really. But nobody uses liquid so 🤷‍♂️
