Electrum rabbit hole? Sounds like you're setting up a server?
I've got electrs on my raspi and it does well enough for me. Been meaning to move from btc-rpc-explorer to esplora.
One day gonna get a refurb to do lnd, but probably looking for an all in one rather than a laptop. Though the battery as built in UPS aint bad... just gotta turn off the modern acpi power controls that kill things when the monitor closes.
