Let me be a bit more specific. If you are doing a couple of light services + jellyfin, maybe you can pull it off. But if you have some critical latency sensitive applications + jellyfin, it can cause issues at random times.
Also, if you are ONLY hosting Jellyfin with no *arr stack, you should be fine. I made that mistake and my Pi went down to a crawl.
Test your services together, and based on that decide on the subset of services.

Woah. I ran it on my 4GB Pi and it was running very slow. Which Pi are you using? I eventually moved to a mini PC because I was afraid of a microSD card fail + I also had to run Minecraft 😝
