Ensuring adequate security when hosting servers from desktop

[willhub]

Hi, apologies if this is wrong section if a mod can move it if they think so.

I run some services from my desktop that I access over the internet.

Streaming the desktop for gaming
torrent UI
Streaming app UI
Plex
Minecraft Server & UI
Remote access for accessing the storage and transferring files

Additionally I want to host a simple website from my PC.

I've got a few ports forwarded for certain apps that won't use UPNP.

I'm using YouFibre, static IP and an Eero router.

Any steps I should be doing re security, I'm accessing these services simply with the IP & port relevant to the app.
