A few solid options: Njalla accepts Lightning directly and is privacy-friendly. LunaNode takes BTC and has decent specs for the price. Bitlaunch lets you spin up VPS on DigitalOcean/Vultr/UpCloud and pay with Lightning. For bare metal, Privex and 1984hosting both accept Bitcoin. If you want something more grassroots, check out Noderunners.org — community-run and Lightning-native.
