I saw your concern about backdoors in the machines of users in other comments. Its pretty simple to replace your phone and computer's OS with a FOSS alternative. Graphene OS and Calyx OS for smartphones, privacy centric Linux distros like Tails for PC. Not sure if FreeBSD has a Bitcoin implementation, but its worth checking out. For on-chain funds, you can keep your seed off a machine and only load it up when you want to transact. See the SeedSigner.

I think that lightning is not only practical but probably recommended because its more private than on-chain transactions. Its not perfectly private in any sense, but its better than nothing.
