Someone said one named Zeus is the only non custodial wallet but you have to run a lightning node. You’ll be charged fees otherwise.

It's a bit of work to manage your own lightning node. You have to open liquidity channels which is going to take some time to learn about and manage.
Phoenix Wallet is an ok compromise. Non-custodial but they manage the channels for you, probably for a fee.
If just looking to test things, I wouldn't overthink it for now. Wallet of Satoshi works.
Blixt is my new fave for a non custodial private channel lightning wallet. Can choose if you want to open the channel to blixt or your own node but I found it doesnt work well commenting to my cln node. Probs works fine if your node is lnd.
