Lightning is the best (when it works haha). You still have to know inbound/outbound liquidity but it's gotten a lot better in the past 2-3 years.
Check out these non custodial options:
@ZEUS makes an amazing phone wallet
Phoenix wallet is fantastic
Raspiblitz runs a lightning node on your own raspi
@Start9 makes an unbelievable ecosystem and a large step up from raspiblitz
@Coinos is super simple wallet to onboard normoes and is nice to transition from non-kyc/centralized to self custodial.
Ecash and cashu are incredible projects and stable but still early.
@KoalaSat can help buy/sell on lightning.
There's a lot happening on bitcoin layer 2/3!
