I use Ubuntu Server on my home servers. Been running it on them for years without issue. I know Canonical/Ubuntu get a lot of hate in the linux community, but for server side things, I think it's great.
- If you use an LTS (24.04) version, you can get super long term security updates, meaning you don't have to worry about a full os upgrade for 10-15 years (via the free Ubuntu pro).
- It's super solid, boring, and dependable, which is what you want out of a server os
- If you need it, there's a TON of documentation/support information out there for Ubuntu.
