I found SwiftServers and it is a professional Minecraft hosting platform that is totally free to use. It is made to avoid the usual free host problems like queues and lag.
They use a custom control panel they built from scratch and it feels focused on being lightweight and easy. You can spin up a vanilla SMP with friends or run a Paper server fast.
They support multiple server types like Paper and Spigot and Fabric plus Hytale and Luanti and ClassiCube. Security is a big deal here with DDoS protection and a backup system so you can create and restore quickly.
The free plan includes 8 GB RAM with a Ryzen 5 3600 and 10 GB NVMe SSD and a 1 Gbit uplink. They also say there is no player slot cap and no credit card needed.

GG.MINEWIND.NET New Server IPUK Survival Stress Test Server

I found a brand new UK survival server that is mainly here for stress testing and performance checks. The owner is mixing Azure hosting with Minecraft and wants players to jump in and see how it feels.
It runs on Paper 1.21 and the gamemode is Survival. The server is hosted in the UK on Azure UK South so it should feel snappy for UK players.
If you join the test server you are basically helping them push the infrastructure and report if anything feels laggy or weird. They also offer free 48 hour server trials for anyone who wants to try running their own server.
