If you can dedicate some time to constant keep up - pick a rolling distro. Doing major version upgrades has never not had problems for me. Every major distro has one.
My choice is Gentoo, but I’m weird like that. Having said that - my email server has been running happily on Arch for just over 5 years now.
The lemmy instance I host is on Debian testing - Gentoo was not available on DO - no issues so far.
Even when it’s mostly containers - why waste time every n years doing the big upgrade? Small change is always safer.
Of course you can! Nginx and wireguard on a VPS and actual services wherever you want.
