Its not that cheap. Alternative to fixed float is boltz. Also I wouldn't use muun as a lightning wallet.
Why not use Muun in this situation? I undertand it is not an actual Lightning Wallet, but it is cheap / easy as a custodial option.

As long as you know that its not a LN wallet. If you can control the amount of sats/vb then its equal to most other onchain wallets. But I'm not sure you can do this with muun, which is why I say its not cheap.
