I found SwiftServers and it is a free Minecraft hosting platform that tries to not be the usual laggy free host thing. It has a custom control panel that they built themselves and it looks like it is meant to be fast and easy to use.
You can spin up a server really quick for a vanilla SMP with friends or a Paper server. They also say you can run other server types too like Spigot Fabric Hytale Luanti and ClassiCube.
They talk a lot about safety with DDoS protection and a backup system so you can create backups and restore fast. The plan they show includes 8 GB RAM a Ryzen 5 3600 CPU 10 GB NVMe SSD storage a 1 Gbit uplink and they say they do not cap player slots.
They also say it is really free with no credit card and no hidden fees.
