perfectly fine. A LND node in neutrino mode will not use too much resources like a full core node. And less space too. A RPi with just LND in neutrino mode and Alby Hub will take very few resources. I am strongly suggest to not go with Umbrel crap. Just use plain simple LND install + Alby Hub and you are good to go. KISS = Keep it simply stupid.

What you should be aware is the ping to your neutrino peers. In the Zeus guide I've explained why this matters and what alternatives you have for neutrino peers. You can set any of those peers to connect. https://darth-coin.github.io/wallets/getting-started-zeus-wallet-en.html Please read it.
