wireless access locally and security question

[galoor]

just to be clear i'm a complete beginner only in the learning process atm as to how Jellyfin (as well as Arr apps) works.
so a bit more context to my main question:
I dont intent to access/stream my Jellyfin outside of my LAN and only use it at home cause I don't want to deal with all the network security processes that I have to do just to make it work. I'm not really a tech savy, esp when it comes to networking security. I know little to NOTHING about it.
so,
1. I wanted to be able to access my Jellyfin(medias are in my main PC connected via ethernet) on my Smart TV (connected via Wifi) but wondering if wirelessly accessing them locally(via wifi) counts as LOCAL (LAN) or Remote access?
i'm trying to figure this out if I need to set up some sort of VPN(like Tailscale) to securely access my Jellyfin within my (local) wirelessly connected device/s.

2. if there's still some sort of vulnerabilities outside of my LAN even when using Jellyfin locally, what security measures should I do and what vulnerabilities should I worry about?

and please try to ELI5 answer if its too technical. i'm not that brilliant lol
thanks.

1. wifi / wired are all considered LAN access (assuming you dont have a complicated home network, it seems like no) . Unless you have other users that are sniffing (specifically pulling your logs) traffic on your lan, you shouldnt have to worry about 'securing it' .
2. your router/firewall typically do a good enough job of protecting you. only if you do port forwarding do you expose internal to external.

Basically what gaming09 said. In typical wifi routers ethernet and wifi are in same subnet, like 192.168.0.0/24 or 192.168.1.0/24. You can check ip address of your jellyfin and smart tv to find out. Its not remote access unless you want, like your friends, to access your jellyfin from their own wifi/lan, that's when you need tailscale or similar.

If you are unsure, open terminal/cmd prompt on your jellyfin system and try pinging the smart tv wifi ip (like ping 192.168.0.222). If pings shows something like 64ms one after another, your devices are probably in same lan

ah...that clarifies it. thanks everyone! sorry if the question seems dumb lol . i only started learning about this recently
