id suggest going with the albyhub LDK lightnode that you can setup in start9 via their service, it's more lightweight than running LND / btc core node, and i dont think you need anything more than the albyhub LDK for what you want as a setup. Once you configure and set up the service on start9, you could open a channel with an LSP like megalith, swap some sats out to create from liquidity from within the service, and you'd be set with a better experience imo.
