I found a Minecraft hosting option called Stellara Servers and it is made for people who want their server to run smooth. It seems like a good pick if you are starting fresh or switching hosts.
They talk a lot about fast hardware so you get low lag and stable TPS even when you use mods and plugins. They also say it works with modpacks and custom jars so it sounds flexible.
Setup is instant so you can get going fast. The control panel is supposed to be simple and they say support is helpful and responds quick.
There is also a first month discount deal listed with a code. If you are trying to plan for like 10 to 20 players it sounds like they are open to questions about what to choose.
