🤔 I too spent some time installing this kind of stack from scratch. I switched to litd recently, because I wanted to try lightning terminal. I think most setups use litd now (it has lnd built in, and is basically the same thing but with a few extras).
For multiple wallets, lnbits handles this for me (with either lnd or litd) I know the recent trend has been to shit on lnbits but I haven't had any probs with it for over a year now.
