Have fun with that rabbit hole of complication.
LN non custodial requires a whole bunch of steps, theory and understanding.

I'm at that level already. Not too much of a hassle for me anymore, except for the hot wallet risk.
But yes, getting off ground can be troublesome.
I recommend Blixt wallet for starters which do not eant to route or just play around with a few channels on an android with routing.
Then move to raspiblitz until you are ready for some beefy hardware with self install - probably guided by raspibolt the first time.
And have an eye on the sphinx.chat dedicated aigning device. Promises segregation of logic and signing qith possibility for rules (just sign net zero or net positive events aka routing) and don't sign withdrawals automatically.
